Please read the following notes regarding this release.
  • The Digital Object Identifier (DOI) metadata for this product and required citation is at https://commons.datacite.org/doi.org/10.25925/20210518.
  • In this release all time variable definitions have been changed. Time variables will now be at the midpoint of the interval for time-averaged values where previously time was at the start of the interval for time-averaged values. Please be sure to read the variable definitions in header metadata.
  • In addition, the start time, which is the time at the start of the interval for time-averaged values, will be be included as variable start_time.
  • Two new columns have been added to the assimilation_concerns variable.
  • The column under review will be 1 (true) if the observation has an unconfirmed reason that would indicate the measurement may not be valid.
  • The column wdcgg-background will be 1 (true) if the observation has been given a valid non-background QCflag in the source WDCGG dataset.
  • Both of the above additions to assimilation_concerns are not considered in the determination of suitability for assimilation into a global scale model.
  • A mistake in the way NOAA flask pairs were calculated led to some cases where more than two flasks were included in each averaged pair. In this release averaged NOAA flasks are now true flasks pairs (with n=2) and individual flasks should be appropriately separated.

  • A mistake in the NOAA flask pair averaging logic did not correctly average instances of the same flask being measured more than once.
  • The logic now correctly averages all samples from a given flask first, and then averages the samples that have the exact same time.
  • The daily file format was not properly compressed in previous releases and is now a much more manageable size.
  • The variable qcflag will now only be of the type character array and can no longer be an integer type variable.
  • The variable obs_num has been removed.
  • The intake heights of several NOAA tower insitu datasets has been adjusted slightly. Please see the list of datasets below.

obspack_ch4_1_GLOBALVIEWplus_v3.0_2021-05-07

This is the third release of the methane GLOBALVIEWplus ObsPack data product. This data package is intended for use in carbon cycle inverse modeling, model evaluation, satellite validation studies, and comparisons with other measurements. Please report bugs and send comments regarding this product to the ObsPack originators. Please read carefully the ObsPack Fair use statement and cite appropriately. Please visit http://gml.noaa.gov/ccgg/obspack/ for more information.

Please read the following notes regarding this release.
  • The Digital Object Identifier (DOI) metadata for this product and required citation is at https://commons.datacite.org/doi.org/10.25925/20210401.
  • This product includes 325 atmospheric methane datasets derived from observations made by 39 laboratories. Data for the period 1983-2019 (where available) are included.
  • In this release all time variable definitions have been changed. Time variables will now be at the midpoint of the interval for time-averaged values where previously time was at the start of the interval for time-averaged values. Please be sure to read the variable definitions in header metadata.
  • In addition, the start time, which is the time at the start of the interval for time-averaged values, will be be included as variable start_time.
  • Two new columns have been added to the assimilation_concerns variable.
  • The column under review will be 1 (true) if the observation has an unconfirmed reason that would indicate the measurement may not be valid.
  • The column wdcgg-background will be 1 (true) if the observation has been given a valid non-background QCflag in the source WDCGG dataset.
  • Both of the above additions to assimilation_concerns are not considered in the determination of suitability for assimilation into a global scale model.
  • A mistake in the way NOAA flask pairs were calculated led to some cases where more than two flasks were included in each averaged pair. In this release averaged NOAA flasks are now true flasks pairs (with n=2) and individual flasks should be appropriately separated.
  • Time variables from EC and LBNL were not consistent with the previous definition of time in past GLOBALVIEWplus products. This issue is fixed along with the new definitions of time.
  • ACT America Air Mass flagging information is now included in the ACT America ObsPack datasets in this product.
  • Data from University of Bristol are now reported as hourly averaged values.
  • The following datasets have been included in this release. Please note this includes datasets that have a new name but have previously been included in ObsPack products.

obspack_ch4_1_GLOBALVIEWplus_v2.0_2020-04-24

This is the second release of the methane GLOBALVIEWplus ObsPack data product. This data package is intended for use in carbon cycle inverse modeling, model evaluation, satellite validation studies, and comparisons with other measurements. Please report bugs and send comments regarding this product to the ObsPack originators. Please read carefully the ObsPack Fair use statement and cite appropriately. Please visit http://gml.noaa.gov/ccgg/obspack/ for more information.

Please read the following notes regarding this release.
  • The Digital Object Identifier (DOI) metadata for this product and required citation is at https://commons.datacite.org/doi.org/10.25925/20200424.
  • This product includes 307 atmospheric methane datasets derived from observations made by 35 laboratories. Data for the period 1983-2018 (where available) are included.
  • The names of ICOS datasets were updated for this release to have more consistent naming and to switch the primary lab to ICOS-ATC (lab 442). As these name changes are significant we have added a global metadata attribute called dataset_alternative_names to help users link new dataset names to their previous versions.
  • The attribute dataset_alternative_names is used to identify all other dataset names that have been used for the record in this dataset. To obtain the full record for this dataset please use all alternatively named datasets that appear in this ObsPack product and the corresponding release of either the CO2 GLOBALVIEWplus or CO2 NRT ObsPacks if applicable.
  • The NOAA surface PFP datasets were previously reported with all intake heights combined into a single dataset. We have decided to separate these intake heights into their own dataset records to better conform to what users expect from a ObsPack dataset.
  • The global metadata attributtes dataset_parse_function, dataset_archive_file and dataset_archive_dir have been removed from ObsPack datasets. These were for internal-use only and were removed to avoid causing confusion among users.
  • Please note that some datasets included in past GLOBALVIEWplus releases are now provided by the ICOS program. The valid data selection scheme for ICOS datasets may differ significantly from the selection scheme provided previously by contributing laboratories.
  • Surface observations from site INX are now all given obs_flag=0 by default.
  • in situ Data from LBNL are now provided in hourly averaged values.
  • The new variable assimilation_concerns is an array with 3 flag values for each measurement. Values in this array indicate if the given observation has the assimilation concern defined by each column. A value of 0 means that there is no concern or it is not known to exist, and a non-zero value means that this concern does exist. Data suitable for assimilation into a global scale model in general will have a 0 in all columns of this variable.
  • Column 1 defines a "time window assimilation concern" for measurements in which a local time window is used to distinguish well-mixed or background signals from other conditions. 0 can mean that the measurement is taken during periods of well-developed PBL mixing, or for downslope flow in mountainous terrain.
  • Column 2 defines a "representivity assimilation concern" for observations where the representativeness is in question. A non-zero value here means that the measurement may have complex signals from factors such as complex terrain.
  • Column 3 defines a "variability assimilation concern" in which temporal variability of high-frequency measurements contributing to the supplied average is considered. Non-zero values mean that the temporal variability exceeds a provider-defined threshold.
  • The following datasets have been included in this release. Please note this includes datasets that have a new name but have previously been included in ObsPack products.

This is a revision of the second release of the SF6 ObsPack product. This data package is intended for use in tracer model evaluation, and comparisons with other measurements. Please report errors and send comments regarding this product to the ObsPack originators. Please read carefully the ObsPack Fair use statement and cite appropriately. Please visit http://gml.noaa.gov/ccgg/obspack/ for more information.

Please read the following notes regarding this release.
  • The Digital Object Identifier (DOI) metadata for this product and required citation is at https://commons.datacite.org/doi.org/10.15138/G3KS7P.
  • This product includes 224 atmospheric sulfur hexafluoride datasets derived from observations made by 12 laboratories. Data for the period 1983-2017 (where available) are included.
  • This release fixes several issues with the HIAPER Pole-to-Pole Observations project (HIPPO) dataset sf6_hip_aircraft-combined_59_allvalid.
    • The dataset is now spilt into two datasets: sf6_hip_aircraft-combined_97_allvalid for NOAA ESRL Halocarbons and Other Atmospheric Trace Species (HATS) data and sf6_hip_aircraft-flask_439_allvalid for University of Miami (UMiami) data.
    • While Harvard University(lab 59) is a key partner for HIPPO data they did not make any SF6 measurements during the HIPPO campaign. Having two separate datasets for each measurement lab should make this more clear for users.
    • Previous versions of obspack_sf6_1 have included data from HIPPO that were not taken on a research flight on 2009-10-20, 2009-10-22, and 2011-09-09. The providers of HIPPO data had not intended for data from these flights to be available in ObsPack so they have been removed for this release.
    • The source of HIPPO data for previous versions of obspack_sf6_1 was discovered to have incorrect timestamps for HIPPO-4 research flight 8. The observation times for HIPPO-4 research flight 8 have been corrected in this ObsPack release.

obspack_sf6_1_v1.1_2017-12-20

This release is a revision to the SF6 ObsPack product. This data package is intended for use in tracer model evaluation, and comparisons with other measurements. Please report errors and send comments regarding this product to the ObsPack originators. Please read carefully the ObsPack Fair use statement and cite appropriately. Please visit http://gml.noaa.gov/ccgg/obspack/ for more information.

Please read the following notes regarding this release.
  • The Digital Object Identifier (DOI) metadata for this product and required citation is at https://commons.datacite.org/doi.org/10.15138/G3HD0M.
  • This product includes 221 atmospheric sulfur hexafluoride datasets derived from observations made by 8 laboratories. Data for the period 1994-2017 (where available) are included.
  • Data measured on a balloon are now given the platform name "balloon-" instead of "aircraft-" for ObsPack dataset names.
  • An update to ObsPack processing for the obspack_sf6_1_v1.0_2017_10_24 release caused all NOAA flasks to be reported as flask pairs where available. ObsPack had previously followed a procedure to average flask pairs into a single value. After review we have decided to revert this change for this release and now all flask pairs will be reported as a single averaged value. This change will affect all NOAA data for surface-flask, surface-pfp, aircraft-flask, and aircraft-pfp datasets.
  • NOAA SF6 flask data are now fully quality controlled through the end of 2016.
  • The number of available datasets has increased for this release. The following is a full list of datasets contained in this product.

  • This NRT ObsPack covers the period 2022-01-01 through 2022-08-31. For data before this period, please use the fully quality-controlled observations in the most-recent GLOBALVIEW+.
  • The Digital Object Identifer (DOI) metadata for this product and required citation is at https://commons.datacite.org/doi.org/10.25925/20220831.
  • The variable qcflag will now only be of the type character array and can no longer be an integer type variable.
  • The variable obs_num has been removed.
  • The intake heights of several NOAA tower insitu datasets has been adjusted slightly.
  • An error in the flask averaging logic for instances where more than 2 flasks were taken at the exact same time has been fixed in this release. All flasks taken at the exact same time are now averaged to a single value appropriately.
  • NOAA surface PFP data have been flagged for cases of ambient H2O > 1.7% v/v. There is evidence that since the sample air is not fully dried, water is condensing on the walls of the flasks, causing CO2 in the measured air to be biased significantly low. This preliminary flagging is subject to change.
  • NOAA Aircraft pfp datasets have been additionally flagged for outliers in this release.

  • A mistake in the NOAA flask pair averaging logic did not correctly average instances of the same flask being measured more than once.
  • The logic now correctly averages all samples from a given flask first, and then averages the samples that have the exact same time.
  • The daily file format was not properly compressed in previous releases and is now a much more manageable size.
  • The SCRIPSS data were not include in this release due to an issue. The data are still included in the most recent GV+ release.

  • This NRT ObsPack covers the period 2021-01-01 through 2021-07-31. For data before this period, please use the fully quality-controlled observations in the most-recent GLOBALVIEW+.
  • The Digital Object Identifer (DOI) metadata for this product and required citation is at https://commons.datacite.org/doi.org/10.25925/20210820.
  • In this release every reported CO2 observation in the value variable is reported on the WMO CO2 X2019 calibration scale.
  • This WMO CO2 X2019 value either has been provided to us by data providers, or we have converted the measurement from the provided measurement scale to the WMO X2019 scale using the best representation currently available.
  • If the data have been converted within ObsPack to the WMO CO2 X2019 scale, we also provide the original measurement values in a new variable called value_original_scale. Please be sure to review the metadata provided in the variable attributes when using value_original_scale, as scale differences of up to 0.2 ppm CO2 are possible.
  • We will continue to work with data providers to make sure that all data have the most accurately determined WMO X2019 value in ObsPack products going forward. We anticipate updates to this product to refine these scale adjustments.

  • One new column has been added to the assimilation_concerns variable.
  • The column scale_conversion will be 1 (true) if the observation was not provided on the WMO CO2 X2019 calibration scale.
  • This addition to assimilation_concerns is not considered in the determination of suitability for assimilation into a global scale model.
  • A mistake in the way NOAA flask pairs were calculated led to some cases where more than two flasks were included in each averaged pair. In this release averaged NOAA flasks are now true flasks pairs (with n=2) and individual flasks should be appropriately separated.

  • The Digital Object Identifer (DOI) metadata for this product and required citation is at https://commons.datacite.org/doi.org/10.25925/20200909.
  • A full list of data providers is at providerlist/obspack_co2_1_NRT_v6.0_2020-09-22.html
  • Please note there are no Environment Canada Near Real-Time data for this release. The currently update EC data can be found in the most recent GLOBALVIEWplus v6.0 product.
  • In this release the time variable definition has been changed. The time variable will now be at the midpoint of the interval for time-averaged values where previously time was at the start of the interval for time-averaged values.
  • For example, data that have been averaged to hourly values from a higher resolution will always have a time at halfway through the hour (XX:30) regardless of the distribution over the hourly interval.
  • In addition, the start time, which is the time at the start of the interval for time-averaged values, will be be included as variable start_time, and the midpoint time, which is the midpoint of the interval for time-averaged values, will be included as variable midpoint_time for users preference.
  • A new variable unique_sample_location_num has been added to all datasets. This variable uniquely identifies a sample location and datetime. The number assigned to each observation in this variable will be the same in all future ObsPack products including ones for other species measured in that sample.
  • Two new columns have been added to the assimilation_concerns variable.
  • The column under review will be 1 (true) if the observation has an unconfirmed reason that would indicate the measurement may not be valid.
  • The column wdcgg-background will be 1 (true) if the observation has been given a valid non-background QCflag in the source WDCGG dataset.
  • Both of the above additions to assimilation_concerns are not considered in the determination of suitability for assimilation into a global scale model.
  • All dataset providers are now listed as authors in the citation. Please be sure to check the updated citation at https://commons.datacite.org/doi.org/10.25925/20200909 and the usage information at citation.php?product=obspack_co2_1_NRT_v6.0_2020-09-22.
  • Based on comparison with in situ measurements at SPO and SYO (from National Institute of Polar Research, Japan), a storage correction was applied to NOAA flask-air samples measured for CO2. The correction is ~0.2 ppm/yr at SPO and 0.08 ppm/yr at SYO. Uncertainty for the correction has not yet been determined and applied to the measurement uncertainty, but it is estimated to be ~0.05 ppm.
  • A mistake in the way NOAA flask pairs were calculated led to some cases where more than two flasks were included in each averaged pair. In this release averaged NOAA flasks are now true flasks pairs (with n=2) and individual flasks should be appropriately separated.

  • Please note that some record where only preliminary data are available may extend back to before 2019-01-01.
  • Individual datasets from ICOS now have their own citations. Please review the dataset metadata and the dataset citations summary file to identify which ICOS datasets are used to construct the given ObsPack dataset.
  • Surface observations from site INX are now all given obs_flag=0 by default.
  • We are working on a new variable to better communicate potential concerns with a given observation.
  • This new variable assimilation_concerns can be used by users who require more information about the suitability of a measurement for certain applications than a simple binary obs_flag can give.
  • assimilation_concerns is an array with 3 flag values for each measurement. Values in this array indicate if the given observation has the assimilation concern defined by each column. A value of 0 means that there is no concern or it is not known to exist, and a non-zero value means that this concern does exist. Data suitable for assimilation into a global scale model in general will have a 0 in all columns of this variable.
  • Column 1 defines a "time window assimilation concern" for measurements in which a local time window is used to distinguish well-mixed or background signals from other conditions. 0 can mean that the measurement is taken during periods of well-developed PBL mixing, or for downslope flow in mountainous terrain.
  • Column 2 defines a "representivity assimilation concern" for observations where the representativeness is in question. A non-zero value here means that the measurement may have complex signals from factors such as complex terrain.
  • Column 3 defines a "variability assimilation concern" in which temporal variability of high-frequency measurements contributing to the supplied average is considered. Non-zero values mean that the temporal variability exceeds a provider-defined threshold.
  • We are committed to working on the implementation of this variable to suit the needs of ObsPack users. The number of columns in the assimilation_concerns array may grow over time as we refine these methods for classifying measurements.
  • 2019-12-27: Remade daily files to include both the surface elevation and intake height variables in all daily files. Both variables are included regardless of their inclusion in the dataset files.

  • The Digital Object Identifer (DOI) metadata for this product and required citation is at https://commons.datacite.org/doi.org/10.25925/20190610.
  • A full list of data providers is at providerlist/obspack_co2_1_NRT_v4.4.2_2019-06-10.html
  • Fixed further inconsistencies with CarbonTracker variables CT_MDM and CT_RMSE that resulted in expected values being missing for observations marked for assimilation.
  • Furthermore the values for CT variables CT_may_localize and CT_may_reject now properly reflect the attribute description where 1=True and 0=False.
  • A bug in the Environment Canada curve fitting routine was preventing observations in the full 12-16 local solartime window from being properly flagged. This has been fixed for this release and the window has been expanded to 10-18 local solartime.

  • The NOAA surface PFP datasets were previously reported with all intake heights combined into a single dataset. We have decided to separate these intake heights into their own dataset records to better conform to what users expect from a ObsPack dataset.
  • We have updated the units of ObsPack variables CT_RMSE and CT_MDM to be consistent. The units of these variables in both netcdf output and daily netcdf output is now mol mol-1.
  • New datasets have been included in this release. Please note this includes datasets that have a new name but have previously been included in NRT products.

obspack_co2_1_NRT_v4.4_2019-05-13

This is a quarterly update of the near-real time (NRT) data product. This data package is intended for use in carbon cycle inverse modeling, model evaluation, satellite evaluation studies, and comparisons with other measurements. In general, the data presented here are preliminary and have not undergone full quality control. Please report bugs and send comments regarding this product to the ObsPack originators. Please read carefully the ObsPack Fair use statement and cite appropriately. Please visit http://gml.noaa.gov/ccgg/obspack/ for more information.

Please read the following notes regarding this release.

  • This NRT ObsPack covers the period 2018-01-01 through 2019-03-31. For data before this period, please use the fully quality-controlled observations in the most-recent GLOBALVIEW+.
  • The Digital Object Identifer (DOI) metadata for this product and required citation is at https://commons.datacite.org/doi.org/10.25925/20190426.
  • A full list of data providers is at providerlist/obspack_co2_1_NRT_v4.4_2019-05-13.html
  • NOAA aircraft PFP data have been flagged for cases of ambient H2O > 1.7% v/v. There is evidence that since the sample air is not dried, water is condensing on the walls of the flasks, causing CO2 in the measured air to be biased significantly low.
  • As this flagging affects the full record of all NOAA aircraft PFP records and this NRT product only contains recent records we have generated full records of these datasets that contain the humidity flagging. That version of these datasets can be downloaded here http://gml.noaa.gov/ccgg/obspack/data.php?id=obspack_co2_1_NOAA_aircraft-pfp_restricted_2019-04-17.
  • The aforementioned ObsPack obspack_co2_1_NOAA_aircraft-pfp_restricted_2019-04-17 has full NOAA aircraft PFP datasets with the values that have been flagged for humidity passed through with obs_flag=0.
  • For more information on the NOAA aircraft PFP humidity flagging please contact Kathryn McKain at kathryn.mckain@noaa.gov

  • The default value for the value_std_dev variable was being set incorrectly when absent in some datasets. Missing value_std_dev values should now be consistent in this version.
  • Please note that some datasets included in past GLOBALVIEWplus releases are now provided by the ICOS program. The valid data selection scheme for ICOS datasets may differ significantly from the selection scheme provided previously by contributing laboratories.
  • A bug in the process that assigned CarbonTracker variables to ObsPack datasets caused some CT_assim values to not have a correctly assigned value. The bug has been fixed in this release. CT_assim now follows the obs_flag variable convention where 1=assimilate and 0=do not assimilate. Please make sure you are using the correct convention for this variable.
  • The global metadata attributtes dataset_parse_function, dataset_archive_file and dataset_archive_dir have been removed from ObsPack datasets. These were for internal-use only and were removed to avoid causing confusion among users.
  • ATom data for missions 3 and 4 were not ready for the most recent release of GLOBALVIEW+ and this NRT release does not cover the time span of both missions. We have released these datsets in an updated version of the ATom product that can be downloaded here http://gml.noaa.gov/ccgg/obspack/data.php?id=obspack_co2_1_ATom_v3.0_2019-04-24.

  • The names of ICOS datasets were updated for this release to have more consistent naming and to switch the primary lab to ICOS-ATC (lab 442). As these name changes are significant we have added a global metadata attribute called dataset_alternative_names to help users link new dataset names to their previous versions.
  • The attribute dataset_alternative_names is used to identify all other dataset names that have been used for the record in this dataset. To obtain the full record for this dataset please use all alternatively named datasets that appear in this ObsPack product and the corresponding release of either the CO2 GLOBALVIEWplus or CO2 NRT ObsPacks if applicable.
  • To further help visualize this change, we have made a table of all dataset names in this NRT product with their alternative names as will appear the header metadata.

obspack_co2_1_NRT_v4.3_2018-10-17

This is a quarterly update of the near-real time (NRT) data product. This data package is intended for use in carbon cycle inverse modeling, model evaluation, satellite evaluation studies, and comparisons with other measurements. In general, the data presented here are preliminary and have not undergone full quality control. Please report bugs and send comments regarding this product to the ObsPack originators. Please read carefully the ObsPack Fair use statement and cite appropriately. Please visit http://gml.noaa.gov/ccgg/obspack/ for more information.

Please read the following notes regarding this release.

  • This NRT ObsPack covers the period 2018-01-01 through 2018-09-30. For data before this period, please use the fully quality-controlled observations in the most-recent GLOBALVIEW+.
  • The Digital Object Identifer (DOI) metadata for this product and required citation is at https://commons.datacite.org/doi.org/10.25925/20181017.
  • A full list of data providers is at providerlist/obspack_co2_1_NRT_v4.3_2018-10-17.html
  • To better represent ObsPack datasets that have citation and licensing information from their source we have added three new metadata attributes. These attributes will appear in the header meatdata of ObsPack datasets where applicable.
    • dataset_provider_citation
    • dataset_identifier
    • dataset_provider_license
  • In addition, this citation and license information will appear in one new product summary file for all datasets named obspack_name_dataset_citations.txt (obspack_co2_1_NRT_v4.3_2018-10-17_dataset_citations.txt).
  • Users are expected to to cite both the ObsPack product citation and the citation for individual data sets used if applicable.

  • We are introducing new variables that are prepared for the CarbonTracker model that other ObsPack users may find useful in their own work.
    • CT_sampling_strategy: Flag indicating how an observation should be sampled from the atmospheric model. Values are: 1 = 4-hour model average; 2 = 1-hour model average; 3 = 90-minute average; 4 = quasi-instantaneous model value.
    • CT_MDM : CarbonTracker model-data mismatch error value (in ppm). This is the error value placed on each measurement in the assimilation system, and is meant to express the statistics of simulated-minus-observed CO2 residuals expected if CarbonTracker were using perfect surface fluxes.
    • CT_RMSE : Root-mean-square error (in ppm CO2) from which the CT_MDM values are generated. These are statistics of model performance for these observations, generated from other simulations.
    • CT_assim : Carbontracker assimilation flag. 0=assimilated, 1=not assimilated, 2=withheld.
    • CT_may_reject: internal CarbonTracker flag; observation is rejectable
    • CT_may_localize: internal CarbonTracker flag; observation may be localized
    • For more information on these new ObsPack variables please contact Andy Jacobson

  • An effort has been made to correctly report the data frequency in ObsPack datasets. Each relevant dataset should now have a consistent "dataset_data_frequency" and "dataset_data_frequency_unit" in the header metadata where applicable.
  • Datasets from ICOS collections are now included in the NRT product. This product uses CO2 datasets from ICOS_ATC_L2_L2-2018.1(https://meta.icos-cp.eu/collections/4H3RS8YtXIt_WTcjrSSkaQ-O).
  • Data for ACT-America Spring 2018 flights are now included in this release.
  • We are experimenting with a new format for distrubuting ObsPack products. Starting with this release we will be providing ObsPack dataset observations in a daily format as well as in the traditional timeseries format.
  • The daily-format files are formatted such that there is one file for each day covered by the product. Each daily file will contain every observation on the corresponding day across all datasets in the ObsPack product. The same measurements are provided in both formats, but they are organized in different files.
  • For the daily-format files, the header metadata for every individual dataset included in all of the daily files can be found in a directory called 'metadata'. Please use the obspack_id to identify the source of any given observation in a daily file.

Please read the following notes regarding this release.

  • This NRT ObsPack covers the period 2017-01-01 through 2018-03-31. For data before this period, please use the fully quality-controlled observations in the most-recent GLOBALVIEW+.
  • The Digital Object Identifer (DOI) metadata for this product and required citation is at https://commons.datacite.org/doi.org/10.15138/G3RP8K.
  • Previously, some insitu data sets reported standard deviation in the value_unc variable/column. Going forward, all insitu data sets will report standard deviation as value_std_dev and measurement uncertainty as value_unc, when available.
  • Data for ACT-America Fall 2017 flights are now included in this release.

  • An update to ObsPack processing for the obspack_co2_1_NRT_v4.0_2017-09-08 release caused all NOAA flasks to be reported as flask pairs where available. ObsPacks had previously followed a procedure to average flask pairs into a single value. After review we have decided to revert this change for NRT_v4.1 and now all flask pairs will be reported as a single averaged value. This change will affect all NOAA data for surface-flask, surface-pfp, aircraft-flask, and aircraft-pfp datasets.
  • The dataset 'co2_mbo_tower-insitu_1_allvalid-10magl' has been renamed to 'co2_mbo_tower-insitu_1_allvalid-11magl' to correct the mislabeled intake height.

obspack_co2_1_NRT_v4.0_2017-09-08

This is the second official release of the near-real time (NRT) data product. This data package is intended for use in carbon cycle inverse modeling, model evaluation, satellite evaluation studies, and comparisons with other measurements. In general, the data presented here are preliminary and have not undergone full quality control. Please report bugs and send comments regarding this product to the ObsPack originators. Please read carefully the ObsPack Fair use statement and cite appropriately. Please visit http://gml.noaa.gov/ccgg/obspack/ for more information.

Please read the following notes regarding this release.

  • This NRT ObsPack covers the period 2017-01-01 through 2017-08-31. For data before this period, please use the fully quality-controlled observations in the most-recent GLOBALVIEW+.
  • The Digital Object Identifer (DOI) metadata for this product and required citation is at https://commons.datacite.org/doi.org/10.15138/G33D0W.
  • Text datasets have returned for this release.
  • To avoid confusion, the text file datasets now contain all of the same variables as the corresponding netcdf file (except for solartime_components).
  • The variable "obs_id" has been removed from all output datasets. Please use the more descriptive id "obspack_id" to identify a specific observation in a given ObsPack. The obspack_id for a given observation is guaranteed to be unique.
  • The variable "id" has been changed to "air_sample_container_id" to better define the purpose of the variable and avoid confusion with other ids defined in ObsPack datasets.
  • The variable "obspack_id" will now be a maximum character length of 200 (previously 100) due to the variable exceeding 100 characters for certain datasets.
  • The variables "gps_altitude" and "pressure_altitude" were added to better represent aircraft campaigns in which both were valid measurements of altitude. This led to certain datasets not containing the default "altitude" variable which was an unwelcome change for users. For consistency we will be using the variable "altitude" in all datasets and this variable will contain the recommended altitude measurement. Please refer to the altitude variable comment if you would like to know more about which measurement is chosen.
  • Additional observations for NOAA flask and PFP datasets have been included to support regional modeling applications. These observations have a NOAA-internal ccg_flag with a second-column alphanumeric character value other than a period (.), indicating that the sample is valid but does not meet selection criteria for use in coarse-resolution global models. These observations will have an obs_flag value of 0.
  • The datacite pages for all ObsPack DOIs have undergone a format change. The new format does not contain a list of providers by default. We will work on an option for those who would like to view more detailed DOI metadata.
  • Atmospheric Tomography Mission (ATom) in situ data have been added to this NRT ObsPack. These observations consist of 1 new CO2 dataset:
    • co2_tom_aircraft-insitu_1_allvalid

obspack_co2_1_NRT_v3.2.1_2017-02-02

This is a minor revision to the obspack_co2_1_NRT_v3.2 data product.

Please read the following notes regarding this revision.

  • This NRT ObsPack covers the period 2016-01-01 through 2016-12-31. For data before this period, please use the fully quality-controlled observations in the most-recent GLOBALVIEW+.
  • The Digital Object Identifer (DOI) metadata for this product and required citation is at https://commons.datacite.org/doi.org/10.15138/G3KW2T.
  • Obspack source code has been further improved to better handle missing values in output datasets.
  • Previously, ObsPack had no documented standard for longitude despite keeping datasets consistent. This allowed for datasets from ACT America (Atmospheric Carbon & Transport) to be prepared with a longitude range of 0° to +360° which is different from what is expected by users. ObsPack will now use -180° to +180° as a standard for all longitude output and ACT America datasets have been updated to reflect this.

obspack_co2_1_NRT_v3.2_2017-01-13

This is a quarterly update of the near-real time (NRT) data product. This data package is intended for use in carbon cycle inverse modeling, model evaluation, satellite evaluation studies, and comparisons with other measurements. In general, the data presented here are preliminary and have not undergone full quality control. Please report bugs and send comments regarding this product to the ObsPack originators. Please read carefully the ObsPack Fair use statement and cite appropriately. Please visit http://gml.noaa.gov/ccgg/obspack/ for more information.

Please read the following notes regarding this release.

  • This NRT ObsPack covers the period 2016-01-01 through 2016-12-31. For data before this period, please use the fully quality-controlled observations in the most-recent GLOBALVIEW+.
  • The Digital Object Identifer (DOI) metadata for this product and required citation is at https://commons.datacite.org/doi.org/10.15138/G3QP4R.
  • ObsPack source code has been further optimized to exclude variables in the output netcdf files for which there is no data for a given dataset.
  • The NRT ObsPack will no longer provide observations in the alternative text file format. Observations are only avilable in netCDF file format.
  • A NOAA Tower in situ dataset for the Carbon in Arctic Reservoirs Vulnerability Experiment (CARVE) has been added to the NRT ObsPack with site code CRV.
  • Environment Canada data have been updated from the previous release.
  • Environment Canada data are preprocessed with an experimental scheme based on the CCG curve fitting routine to flag data that may be inappropriate for assimilation into models. All valid Environment Canada hourly averages are provided in this product; the curve-fitting scheme is used only to set obs_flag values. Compared to the previous NRT release, this filter is slightly less strict in order to permit assimilation of more observations: selected observations outside 4 standard deviations of the smooth curve fit are given obs_flag 0. Previously, this threshold was 3 standard deviations.
  • Due to an issue with the source dataset we are unable to include EC CO2 data from Lac La Biche for this release. We expect this issue to be resolved by the next NRT ObsPack release.
  • ACT America (Atmospheric Carbon & Transport) in situ and PFP data have been added to this NRT ObsPack. These observations consist of 4 new CO2 datasets:
    • co2_act_aircraft-insitu_428_allvalid-b200
    • co2_act_aircraft-insitu_428_allvalid-c130
    • co2_act_aircraft-pfp_1_allvalid-b200
    • co2_act_aircraft-pfp_1_allvalid-c130
  • b200 and c130 in the dataset name indicates the aircraft on which the measurement was taken.
  • A new lab, NASA-LaRC, has been added for the ACT aircraft in situ data.
  • New meteorological variables have been added to ObsPack.
    • temperature: Temperature at time of sampling in Kelvin
    • pressure_altitude: Pressure Altitude in meters above sea level derived from ambient pressure at time of sampling
    • gps_altitude: GPS Altitude in meters above sea level taken at time of sampling
    • u: Eastward (westerly) wind component in meters per second
    • v: Northward (southerly) wind component in meters per second
  • The new variables have been added to ACT America datasets as available and will be expanded in future ObsPack releases.

  • The providers for NOAA datasets have been updated.
  • A number of datasets had discrepancies between the site's latitude and longitude (from the header information in each data file) and the sample latitude and longitude (the position attached to each observation). These two values are set independently due to datasets with a varying position. These values have been adjusted to avoid discrepancies. The following sites are affected:
    • Alert, Nunavut, Canada (ALT)
    • Ny-Alesund, Svalbard, Norway and Sweden (ZEP)

obspack_co2_1_NRT_v3.0_2016-06-06

This is the first official release of the near-real time (NRT) data product. This data package is intended for use in carbon cycle inverse modeling, model evaluation, satellite validation studies, and comparisons with other measurements. The NRT product is planned to be released approximately quarterly following the annual release of the GLOBALVIEW+ product.

This product has been improved from the previous internal release.

  • The name has been changed from obspack_co2_1_CarbonTracker-NRT to obspack_co2_1_NRT to avoid confusion over the contents. The CarbonTracker model is not involved in creating this product.
  • This NRT ObsPack covers the period 2014-12-31 through 2016-03-01. For data before this period, please use the fully quality-controlled observations in the most-recent GLOBALVIEW+.
  • The Digital Object Identifer (DOI) metadata for this product and required citation is at https://commons.datacite.org/doi.org/10.15138/G3CC7P.
  • There is additional manual flagging of recent flask and aircraft data, based on visual inspection of the records.
  • Environment Canada data are now assigned an obs_flag value based on a time window of 12:00 to 16:00 local time instead of 16:00 to 19:00 local time.
  • Environment Canada data are now preprocessed with an experimental scheme based on the CCG curve fitting routine to flag data that may be inappropriate for assimilation into models. All valid Environment Canada hourly averages are provided in this product; the curve-fitting scheme is used only to set obs_flag values.
  • NOAA tower insitu data are now additionally flagged if the calculated uncertainty (see Andrews et al., 2014) for a given observation exceeds 3ppm CO2.

obspack_co2_1_GLOBALVIEWplus_v8.0_2022-08-27

This is the eighth major release of the GLOBALVIEWplus (GV+) cooperative data product. This data package is intended for use in carbon cycle inverse modeling, model evaluation, and satellite evaluation studies. Please report errors and send comments regarding this product to the originators. Please read carefully the Fair Use statement and cite appropriately.

This release includes the following important changes.

  • The Digital Object Identifier (DOI) metadata for this product and required citation is at https://commons.datacite.org/doi.org/10.25925/20220808.
  • This product includes 587 atmospheric carbon dioxide datasets derived from observations made by 66 laboratories from 23 countries. Data for the period 1957-2021 (where available) are included.
  • There have been a few changes to ObsPack variables in this GLOABLVIEWplus release.
  • The variable qcflag will now only be of the type character array and can no longer be an integer type variable.
  • The variable obs_num has been removed.
  • The intake heights of several NOAA tower insitu datasets has been adjusted slightly. Please see the list of datasets below.
  • The compression settings of the daily file format has been improved and the overall filesize of this format has been significantly reduced.
  • An error in the flask averaging logic for instances where more than 2 flasks were taken at the exact same time has been fixed in this release. All flasks taken at the exact same time are now averaged to a single value appropriately.
  • An error in the processing for Scripps CO2 program data (lab number 426) led to times that were reported in LST but mislabeled as UTC. In addition, the reported times were incorrect for 4 sites from this program starting in June 2012 at site SMO, and July 2012 at sites BRW, KUM, and MLO. These errors have been fixed in this release and all lab number 426 datasets will have appropriate UTC times.
  • The empirical scale relationship being used in this product to bring NIES data onto the WMO 2019 CO2 scale is temporary. Results from a scale comparison experiment that is currently underway may change this relationship in future products.
  • Please note that we are investigating an issue at several surface flask sampling sites where the recorded time is inconsistent with what we would typically expect at the site. This investigation will take time and a very small fraction of the data are expected to be affected by the issue.
  • NOAA surface PFP data have been flagged for cases of ambient H2O > 1.7% v/v. There is evidence that since the sample air is not fully dried, water is condensing on the walls of the flasks, causing CO2 in the measured air to be biased significantly low. This preliminary flagging is subject to change.
  • NOAA Aircraft pfp datasets have been additionally flagged for outliers in this release.
  • New datasets have been included in this release. Please note this list includes datasets that have a new name but have previously been included in ObsPack products.

obspack_co2_1_GLOBALVIEWplus_v7.0_2021-08-18

This is the seventh major release of the GLOBALVIEWplus (GV+) cooperative data product. This data package is intended for use in carbon cycle inverse modeling, model evaluation, and satellite evaluation studies. Please report errors and send comments regarding this product to the originators. Please read carefully the Fair Use statement and cite appropriately.

This release includes the following important changes.

  • The Digital Object Identifier (DOI) metadata for this product and required citation is at https://commons.datacite.org/doi.org/10.25925/20210801.
  • This product includes 524 atmospheric carbon dioxide datasets derived from observations made by 63 laboratories from 21 countries. Data for the period 1957-2020 (where available) are included.
  • In this release every reported CO2 observation in the value variable is reported on the WMO CO2 X2019 calibration scale.
  • This WMO CO2 X2019 value either has been provided to us by data providers, or we have converted the measurement from the provided measurement scale to the WMO X2019 scale using the best representation currently available.
  • If the data have been converted within ObsPack to the WMO CO2 X2019 scale, we also provide the original measurement values in a new variable called value_original_scale. Please be sure to review the metadata provided in the variable attributes when using value_original_scale, as scale differences of up to 0.2 ppm CO2 are possible.
  • We will continue to work with data providers to make sure that all data have the most accurately determined WMO X2019 value in ObsPack products going forward. We anticipate updates to this product to refine these scale adjustments.

  • In this release all time variable definitions have been changed. Time variables will now be at the midpoint of the interval for time-averaged values where previously time was at the start of the interval for time-averaged values. Please be sure to read the variable definitions in header metadata.
  • One new column has been added to the assimilation_concerns variable.
  • The column scale_conversion will be 1 (true) if the observation was not provided on the WMO CO2 X2019 calibration scale.
  • This addition to assimilation_concerns is not considered in the determination of suitability for assimilation into a global scale model.
  • A mistake in the way NOAA flask pairs were calculated led to some cases where more than two flasks were included in each averaged pair. In this release averaged NOAA flasks are now true flasks pairs (with n=2) and individual flasks should be appropriately separated.
  • New datasets have been included in this release. Please note this includes datasets that have a new name but have previously been included in ObsPack products.

obspack_co2_1_GLOBALVIEWplus_v6.1_2021-03-01

This is a revision of the sixth major release of the GLOBALVIEWplus (GV+) cooperative data product. This data package is intended for use in carbon cycle inverse modeling, model evaluation, and satellite evaluation studies. Please report errors and send comments regarding this product to the originators. Please read carefully the Fair Use statement and cite appropriately.

This release includes the following important changes.

  • The Digital Object Identifier (DOI) metadata for this product and required citation is at https://commons.datacite.org/doi.org/10.25925/20201204.
  • This product includes 511 atmospheric carbon dioxide datasets derived from observations made by 54 laboratories from 21 countries. Data for the period 1957-2019 (where available) are included.
  • A full list of data providers is at providerlist/obspack_co2_1_GLOBALVIEWplus_v6.1_2021-03-01.html
  • The time frequency for Syowa data from Tohoku University (co2_syo_surface-insitu_8_allvalid) was incorrectly labeled. The correct time frequency is 1 hour.
  • The data selection for Amsterdam Island from LSCE (co2_ams_surface-insitu_11_representative) was incorrectly labeled as representative for marine background conditions. The correct data selection is all valid hourly data. To reflect this change the dataset will now be named co2_ams_surface-insitu_11_allvalid. Non-marine data will be given an obs_flag=0 for this dataset going forward.
  • The ObsPack variable CT_MDM has been updated with CT2019B statistics.
  • A new variable MIP_MDM has been added using OCO-2 v9 MIP model-specific statistics.
  • A new variable MIP_models has been added that gives the names of the models contributing to the variable MIP_MDM.
  • We have revised our classification scheme for measurements into the three categories "assimilate", "withhold-for-cross-validation", and "do-not-assimilate". A more careful classification procedure was developed to ensure that withheld measurements are as independent as possible from assimilation measurements. This new procedure considers measurements across all available datasets at a site, including aircraft profiles and multiple tower levels. A final screening pass is then applied to check for any missed assimilated and withheld measurements falling within certain space and time bounds.
  • New datasets have been included in this release. Please note this includes datasets that have a new name but have previously been included in ObsPack products.

obspack_co2_1_GLOBALVIEWplus_v6.0_2020-09-11

This is the sixth major release of the GLOBALVIEWplus (GV+) cooperative data product. This data package is intended for use in carbon cycle inverse modeling, model evaluation, and satellite evaluation studies. Please report errors and send comments regarding this product to the originators. Please read carefully the Fair Use statement and cite appropriately.

This release includes the following important changes.

  • The Digital Object Identifier (DOI) metadata for this product and required citation is at https://commons.datacite.org/doi.org/10.25925/20200903.
  • This product includes 471 atmospheric carbon dioxide datasets derived from observations made by 54 laboratories from 21 countries. Data for the period 1957-2019 (where available) are included.
  • A full list of data providers is at providerlist/obspack_co2_1_GLOBALVIEWplus_v6.0_2019-09-11.html
  • 2021-01-15: The data selection for Amsterdam Island from LSCE (co2_ams_surface-insitu_11_representative) was incorrectly labeled as representative for marine background conditions. The correct data selection is all valid hourly data.
  • In this release the time variable definition has been changed. The time variable will now be at the midpoint of the interval for time-averaged values where previously time was at the start of the interval for time-averaged values.
  • For example, data that have been averaged to hourly values from a higher resolution will always have a time at halfway through the hour (XX:30) regardless of the distribution over the hourly interval.
  • In addition, the start time, which is the time at the start of the interval for time-averaged values, will be be included as variable start_time, and the midpoint time, which is the midpoint of the interval for time-averaged values, will be included as variable midpoint_time for users preference.
  • A new variable unique_sample_location_num has been added to all datasets. This variable uniquely identifies a sample location and datetime. The number assigned to each observation in this variable will be the same in all future ObsPack products including ones for other species measured in that sample.
  • Two new columns have been added to the assimilation_concerns variable.
  • The column under review will be 1 (true) if the observation has an unconfirmed reason that would indicate the measurement may not be valid.
  • The column wdcgg-background will be 1 (true) if the observation has been given a valid non-background QCflag in the source WDCGG dataset.
  • Both of the above additions to assimilation_concerns are not considered in the determination of suitability for assimilation into a global scale model.
  • All dataset providers are now listed as authors in the citation. Please be sure to check the updated citation at https://commons.datacite.org/doi.org/10.25925/20200903 and the usage information at citation.php?product=obspack_co2_1_GLOBALVIEWplus_v6.0_2020-09-11.
  • Based on comparison with in situ measurements at SPO and SYO (from National Institute of Polar Research, Japan), a storage correction was applied to NOAA flask-air samples measured for CO2. The correction is ~0.2 ppm/yr at SPO and 0.08 ppm/yr at SYO. Uncertainty for the correction has not yet been determined and applied to the measurement uncertainty, but it is estimated to be ~0.05 ppm.
  • A mistake in the way NOAA flask pairs were calculated led to some cases where more than two flasks were included in each averaged pair. In this release averaged NOAA flasks are now true flasks pairs (with n=2) and individual flasks should be appropriately separated.
  • Time variables from EC and LBNL were not consistent with the previous definition of time in past GLOBALVIEWplus products. This issue is fixed along with the new definitions of time.
  • ACT America Air Mass flagging information is now included in the ACT America ObsPack datasets in this product.
  • Data from University of Bristol are now reported as hourly averaged values.
  • CONTRAIL aircraft insitu data now have the level-flight data averaged from 1-minute resolution to a 5-minute resolution. This change reduces the number of datapoints in this dataset by a siginificant amount for ease of use.
  • The bug that caused 2 flights to be missing from the ATom campaign in earlier ObsPack products has been fixed in this release.
  • The position of dataset co2_wsd_tower-insitu_60_allvalid was incorrect in previous releases and has been fixed in this release.
  • The time variable in dataset co2_gsfc_aircraft-insitu_430_allvalid was not being set correctly in previous releases and has been fixed in this release.
  • New datasets have been included in this release. Please note this includes datasets that have a new name but have previously been included in ObsPack products.

obspack_co2_1_GLOBALVIEWplus_v5.0_2019-08-12

This is the fifth major release of the GLOBALVIEWplus (GV+) cooperative data product. This data package is intended for use in carbon cycle inverse modeling, model evaluation, and satellite evaluation studies. Please report errors and send comments regarding this product to the originators. Please read carefully the Fair Use statement and cite appropriately.

This release includes the following important changes.

  • The ATom dataset in this product has a known bug that will be fixed in v6.0. Please download the Atom product obspack_co2_1_ATom_v4.0_2020-04-06 for a corrected version of this ATom dataset. Notes on the bug can be read here.
  • The Digital Object Identifier (DOI) metadata for this product and required citation is at https://commons.datacite.org/doi.org/10.25925/20190812.
  • This product includes 460 atmospheric carbon dioxide datasets derived from observations made by 54 laboratories from 21 countries. Data for the period 1957-2018 (where available) are included.
  • A full list of data providers is at providerlist/obspack_co2_1_GLOBALVIEWplus_v5.0_2019-08-12.html
  • 2021-01-15: The data selection for Amsterdam Island from LSCE (co2_ams_surface-insitu_11_representative) was incorrectly labeled as representative for marine background conditions. The correct data selection is all valid hourly data.
  • Individual datasets from ICOS now have their own citations. Please review the dataset metadata and the dataset citations summary file to identify which ICOS datasets are used to construct the given ObsPack dataset.
  • Some COBRA flask and PFP flask data may have mistakenly been made avilable in previous GLOBALVIEWplus releases. Please use this version going forward while we work to sort out the rest of the COBRA data.
  • Surface observations from site INX are now all given obs_flag=0 by default.
  • in situ Data from LBNL are now provided in hourly averaged values.
  • An inconsistency in ObsPack processing for Scripps data allowed for rejected observations to be passed through with obs_flag=0. Rejected data are now properly excluded from Scripps ObsPack datasets.
  • We are working on a new variable to better communicate potential concerns with a given observation.
  • This new variable assimilation_concerns can be used by users who require more information about the suitability of a measurement for certain applications than a simple binary obs_flag can give.
  • assimilation_concerns is an array with 3 flag values for each measurement. Values in this array indicate if the given observation has the assimilation concern defined by each column. A value of 0 means that there is no concern or it is not known to exist, and a non-zero value means that this concern does exist. Data suitable for assimilation into a global scale model in general will have a 0 in all columns of this variable.
  • Column 1 defines a "time window assimilation concern" for measurements in which a local time window is used to distinguish well-mixed or background signals from other conditions. 0 can mean that the measurement is taken during periods of well-developed PBL mixing, or for downslope flow in mountainous terrain.
  • Column 2 defines a "representivity assimilation concern" for observations where the representativeness is in question. A non-zero value here means that the measurement may have complex signals from factors such as complex terrain.
  • Column 3 defines a "variability assimilation concern" in which temporal variability of high-frequency measurements contributing to the supplied average is considered. Non-zero values mean that the temporal variability exceeds a provider-defined threshold.
  • We are committed to working on the implementation of this variable to suit the needs of ObsPack users. The number of columns in the assimilation_concerns array may grow over time as we refine these methods for classifying measurements.
  • New datasets have been included in this release. Please note this includes datasets that have a new name but have previously been included in ObsPack products.

obspack_co2_1_GLOBALVIEWplus_v4.2.2_2019-06-05

This is a revision of the fourth major release of the GLOBALVIEWplus (GV+) cooperative data product. This data package is intended for use in carbon cycle inverse modeling, model evaluation, and satellite evaluation studies. Please report errors and send comments regarding this product to the originators. Please read carefully the Fair Use statement and cite appropriately.

This release includes the following important changes.

  • The Digital Object Identifier (DOI) metadata for this product and required citation is at https://commons.datacite.org/doi.org/10.25925/20190605.
  • This product includes 438 atmospheric carbon dioxide datasets derived from observations made by 52 laboratories from 20 countries. Data for the period 1957-2017 (where available) are included.
  • A full list of data providers is at providerlist/obspack_co2_1_GLOBALVIEWplus_v4.2.2_2019-06-05.html
  • 2021-01-15: The data selection for Amsterdam Island from LSCE (co2_ams_surface-insitu_11_representative) was incorrectly labeled as representative for marine background conditions. The correct data selection is all valid hourly data.
  • Fixed further inconsistencies with CarbonTracker variables CT_MDM and CT_RMSE that resulted in expected values being missing for observations marked for assimilation.
  • Furthermore the values for CT variables CT_may_localize and CT_may_reject now properly reflect the attribute description where 1=True and 0=False.
  • A bug in the Environment Canada curve fitting routine was preventing observations in the full 12-16 local solartime window from being properly flagged. This has been fixed for this release and the window has been expanded to 10-18 local solartime.

Please report errors and send comments regarding this product to the originators. Please read carefully the Fair Use statement and cite appropriately.

This release includes the following important changes.

  • The Digital Object Identifier (DOI) metadata for this product and required citation is at https://commons.datacite.org/doi.org/10.25925/20190520.
  • This product includes 438 atmospheric carbon dioxide datasets derived from observations made by 52 laboratories from 20 countries. Data for the period 1957-2017 (where available) are included.
  • A full list of data providers is at providerlist/obspack_co2_1_GLOBALVIEWplus_v4.2.1_2019-05-20.html
  • 2021-01-15: The data selection for Amsterdam Island from LSCE (co2_ams_surface-insitu_11_representative) was incorrectly labeled as representative for marine background conditions. The correct data selection is all valid hourly data.
  • NOAA aircraft PFP data have been flagged for cases of ambient H2O > 1.7% v/v. There is evidence that since the sample air is not dried, water is condensing on the walls of the flasks, causing CO2 in the measured air to be biased significantly low.
  • As this flagging affects the full record of all NOAA aircraft PFP records and this NRT product only contains recent records we have generated full records of these datasets that contain the humidity flagging. That version of these datasets can be downloaded here http://gml.noaa.gov/ccgg/obspack/data.php?id=obspack_co2_1_NOAA_aircraft-pfp_restricted_2019-04-17.
  • The aforementioned ObsPack obspack_co2_1_NOAA_aircraft-pfp_restricted_2019-04-17 has full NOAA aircraft PFP datasets with the values that have been flagged for humidity passed through with obs_flag=0.
  • For more information on the NOAA aircraft PFP humidity flagging please contact Kathryn McKain at kathryn.mckain@noaa.gov

  • Please note that some datasets included in past GLOBALVIEWplus releases are now provided by the ICOS program. The valid data selection scheme for ICOS datasets may differ significantly from the selection scheme provided previously by contributing laboratories.
  • The global metadata attributtes dataset_parse_function, dataset_archive_file and dataset_archive_dir have been removed from ObsPack datasets. These were for internal-use only and were removed to avoid causing confusion among users.
  • The NOAA surface PFP datasets were previously reported with all intake heights combined into a single dataset. We have decided to separate these intake heights into their own dataset records to better conform to what users expect from a ObsPack dataset.
  • A bug in the process that assigned CarbonTracker variables to ObsPack datasets caused some CT_assim values to not have a correctly assigned value. The bug has been fixed in this release. CT_assim now follows the obs_flag variable convention where 1=assimilate and 0=do not assimilate. Please make sure you are using the correct convention for this variable.
  • Additionally we have updated the units of ObsPack variables CT_RMSE and CT_MDM to be consistent. The units of these variables in both netcdf output and daily netcdf output is now mol mol-1.
  • The names of ICOS datasets were updated for this release to have more consistent naming and to switch the primary lab to ICOS-ATC (lab 442). As these name changes are significant we have added a global metadata attribute called dataset_alternative_names to help users link new dataset names to their previous versions.
  • The attribute dataset_alternative_names is used to identify all other dataset names that have been used for the record in this dataset. To obtain the full record for this dataset please use all alternatively named datasets that appear in this ObsPack product and the corresponding release of either the CO2 GLOBALVIEWplus or CO2 NRT ObsPacks if applicable.
  • New datasets have been included in this release. Please note this includes datasets that have a new name but have previously been included in NRT products.

  • To better represent ObsPack datasets that have citation and licensing information from their source we have added three new metadata attributes. These attributes will appear in the header meatdata of ObsPack datasets where applicable.
    • dataset_provider_citation
    • dataset_identifier
    • dataset_provider_license
  • In addition, this citation and license information will appear in one new product summary file for all datasets named obspack_name_dataset_citations.txt (obspack_co2_1_NRT_v4.3_2018-10-17_dataset_citations.txt).
  • Users are expected to to cite both the ObsPack product citation and the citation for individual data sets used if applicable.

  • We are introducing new variables that are prepared for the CarbonTracker model that other ObsPack users may find useful in their own work.
    • CT_sampling_strategy: Flag indicating how an observation should be sampled from the atmospheric model. Values are: 1 = 4-hour model average; 2 = 1-hour model average; 3 = 90-minute average; 4 = quasi-instantaneous model value.
    • CT_MDM : CarbonTracker model-data mismatch error value (in ppm). This is the error value placed on each measurement in the assimilation system, and is meant to express the statistics of simulated-minus-observed CO2 residuals expected if CarbonTracker were using perfect surface fluxes.
    • CT_RMSE : Root-mean-square error (in ppm CO2) from which the CT_MDM values are generated. These are statistics of model performance for these observations, generated from other simulations.
    • CT_assim : Carbontracker assimilation flag. 0=assimilated, 1=not assimilated, 2=withheld.
    • CT_may_reject: internal CarbonTracker flag; observation is rejectable
    • CT_may_localize: internal CarbonTracker flag; observation may be localized
    • For more information on these new ObsPack variables please contact Andy Jacobson

  • An effort has been made to correctly report the data frequency in ObsPack datasets. Each relevant dataset should now have a consistent "dataset_data_frequency" and "dataset_data_frequency_unit" in the header metadata where applicable.
  • Datasets from ICOS collections are now included in the GLOBALVIEWplus product. This product uses CO2 datasets from ICOS_ATC_L2_L2-2018.1(https://meta.icos-cp.eu/collections/4H3RS8YtXIt_WTcjrSSkaQ-O).
  • We are experimenting with a new format for distrubuting ObsPack products. Starting with this release we will be providing ObsPack dataset observations in a daily format as well as in the traditional timeseries format.
  • The daily-format files are formatted such that there is one file for each day covered by the product. Each daily file will contain every observation on the corresponding day across all datasets in the ObsPack product. The same measurements are provided in both formats, but they are organized in different files.
  • For the daily-format files, the header metadata for every individual dataset included in all of the daily files can be found in a directory called 'metadata'. Please use the obspack_id to identify the source of any given observation in a daily file.

  • Please note that the above list includes two datasets that have an updated name from previous GLOBALVIEW plus releases.
    • co2_fik_surface-flask_11_representative has been updated to co2_fkl_surface-flask_11_representative
    • co2_osi_tower-insitu_68_allhours has been separated into co2_osi_tower-insitu_68_allhours-269magl and co2_osi_tower-insitu_68_allhours-31magl to provide separate datasets for the two intake heights at the site.

  • Previously, some in situ data sets reported standard deviation in the value_unc variable/column. Going forward, all in situ data sets will report standard deviation as value_std_dev and measurement uncertainty as value_unc, when available.
  • The text file format has been updated in an effort to make it more machine readable.
  • The number of headerlines is now always contained in the first line of the text file and counts to the line immediately before the start of the data record.
  • The last line in the text file header info, which contains column names for the data record, now has no # at the start of the line.

  • An update to ObsPack processing for the obspack_co2_1_GLOBALVIEWplus_v3.0_2017-08-11 release caused all NOAA, IPEN, and CSIRO flasks to be reported as flask pairs where available. GLOBALVIEWplus ObsPacks had previously followed a procedure to average flask pairs into a single value. After review we have decided to revert this change for GLOBALVIEWplus_v3.2 and now all flask pairs will be reported as a single averaged value. This change will affect all NOAA, IPEN, and CSIRO data for surface-flask, surface-pfp, aircraft-flask, and aircraft-pfp datasets.
  • The record at Schauinsland (SSL,co2_ssl_surface-insitu_107_allvalid) was mistakenly shortened to only the most recently reproccessed years instead of the full record. The full record at this site has been restored for this release.

obspack_co2_1_GLOBALVIEWplus_v3.0_2017-08-11

This is the third major release of the GLOBALVIEWplus (GV+) cooperative data product. This data package is intended for use in carbon cycle inverse modeling, model evaluation, and satellite validation studies. Please report errors and send comments regarding this product to the originators. Please read carefully the Fair Use statement and cite appropriately.

This release includes the following important changes.

  • The Digital Object Identifier (DOI) metadata for this product and required citation is at https://commons.datacite.org/doi.org/10.15138/G3CW4Q.
  • This product includes 349 atmospheric carbon dioxide datasets derived from observations made by 46 laboratories from 19 countries. Data for the period 1957-2016 (where available) are included.
  • The following labs are now contributing to GLOBALVIEWplus.
    • NASA Langley Research Center (NASA-LaRC), USA
    • Penn State University (PSU), USA
    • University of Minnesota (UOFMN), USA
    • California Institute of Technology, Division of Geological and Planetary Science (CALTECH), USA
    • Utah Atmospheric Trace gas & Air Quality (U-ATAQ), USA

  • There is a new method for representing aircraft campaigns in ObsPack datasets. For all new aircraft campaigns included in ObsPack that do not have an already well defined site code, we will be using a common site code based on the providing lab. For example, new aircraft campaign datasets from NASA-LaRC are given the site code "LARC". Additional metadata fields beginning with "campaign"("campaign_name","campaign_num","campaign_abbr","campaign_logo","campaign_url") have been added to identify information from each campaign. Additionally, to distinguish the names of aircraft campaign datasets created this way, the campaign abbreviation (campaign_abbr) is used in constructing the dataset name rather than the site_code.

  • To better organize the addition of auxillary parameters in ObsPack, for all datasets with water vapor (H2O) measurements, we will be merging the H2O measurements into the CO2 datasets. As this GLOBALVIEWplus is a CO2 product, the "value" variable in each dataset will always contain CO2 measurments. Any auxillary parameters, such as H2O, will be defined in a variable named after the parameter. For this product, water vapor will be in a variable named "H2O".
  • The lab and provider metadata have been expanded to include a "parameter" field (lab_#_parameter, provider_#_parameter). This field is used to associate the lab or provider with a given measurement in the dataset.
  • To avoid confusion, the text file datasets now contain all of the same variables as the corresponding netcdf file (except for solartime_components).
  • The variable "obs_id" has been removed from all output datasets. Please use the more descriptive id "obspack_id" to identify a specific observation in a given ObsPack. The obspack_id for a given observation is guaranteed to be unique.
  • The variable "id" has been changed to "air_sample_container_id" to better define the purpose of the variable and avoid confusion with other ids defined in ObsPack datasets.
  • The variable "obspack_id" will now be a maximum character length of 200 (previously 100) due to the variable exceeding 100 characters for certain datasets.
  • The variables "gps_altitude" and "pressure_altitude" were added to better represent aircraft campaigns in which both were valid measurements of altitude. This led to certain datasets not containing the default "altitude" variable which was an unwelcome change for users. For consistency we will be using the variable "altitude" in all datasets and this variable will contain the recommended altitude measurement. Please refer to the altitude variable comment if you would like to know more about which measurement is chosen.
  • Additional observations for NOAA flask and PFP datasets have been included to support regional modeling applications. These observations have a NOAA-internal ccg_flag with a second-column alphanumeric character value other than a period (.), indicating that the sample is valid but does not meet selection criteria for use in coarse-resolution global models. These observations will have an obs_flag value of 0.
  • The datacite pages for all ObsPack DOIs have undergone a format change. The new format does not contain a list of providers by default. We will work on an option for those who would like to view more detailed DOI metadata.

obspack_co2_1_GLOBALVIEWplus_v2.1_2016-09-02

This release of GLOBALVIEWplus (GV+) is a revision to the previous release. This data package is intended for use in carbon cycle inverse modeling, model evaluation, and satellite validation studies. Please report bugs and send comments regarding this product to the originators. Please read carefully the Fair Use statement and cite appropriately.

This product includes the following revisions.

  • A number of datasets had discrepancies between the site's latitude and longitude (from the header information in each data file) and the sample latitude and longitude (the position attached to each observation). These two values are set independently due to datasets with a varying position. These values have been adjusted to avoid discrepancies. The following sites are affected:
    • Alert, Nunavut, Canada (ALT)
    • Tacolneston, United Kingdom (TAC)
    • Ny-Alesund, Svalbard, Norway and Sweden (ZEP)
  • Minor typos in the obspack summary section files have been corrected.
  • Corrected a bug in the Martha's Vineyard (MVY) dataset that was setting elevation=latitude when processing the raw data.
  • The providers for NOAA datasets have been updated.
  • This product includes 264 atmospheric carbon dioxide and 6 atmospheric water vapor records derived from observations made by 40 laboratories from 19 countries. Data for the period 1957-2015 (where available) are included.
  • The Digital Object Identifer (DOI) metadata for this product and required citation is at https://commons.datacite.org/doi.org/10.15138/g3059z.

  • New variables have been introduced for this release.
    • Water vapor has been added as a parameter for HIP, texaqs2006, arcpac2008, calnex2010, senex2013, and songnex2015. The water vapor measurements will appear as the value field in separate datasets of the form h2o_hip_aircraft-insitu_97_allvalid (h2o_site_project_lab#_selection). The water vapor measurements have been standardized to parts-per-million-by-volume (ppmv) for this release. Please review the metadata in the data files for more information on how the measurements were included.
    • The variable “source_id” has been added to identify or provide context for a particular observation in the source data. It generally contains identifying information used by upstream data providers. For HIP, texaqs2006, arcpac2008, calnex2010, senex2013 this variable can be used to cross reference the H2O and CO2 data as the source_id will be identical for corresponding samples. Please see the netcdf file metadata for more information on this variable.
    • The variable “flight_id” has been added for if data item was sourced from an air campaign, the data provider can optionally provide a flight identification string. Please see the variable comment in the netcdf file metadata for more information on this variable if it is available.
    • The variable “profile_id” has been added, generally for aircraft or shipboard programs, that can be used to identify unique profiles in the data. Please see the variable comment in the netcdf file metadata for more information on this variable if it is available.

  • The dataset summary included in the summary section of the ObsPack now has an extended version of dataset information rather than a simple table.
  • The “qc_flag” variable is no longer included in datasets from NIWA.
  • NCAR data is now assigned obs_flag 1 or 0 based on the QC flag provided by NCAR.
  • This ObsPack now includes Scripps Institution of Oceanography CO2 data from their CO2 program in addition to their O2 program. Due to details of the ObsPack code structure, the new project has been assigned lab number = 426 to differentiate between the two programs.
  • Environment and Climate Change Canada (ECC, formerly Environment Canada) data are now assigned an obs_flag value based on a time window of 12:00 to 16:00 local time instead of 16:00 to 19:00 local time. Furthermore, these data are now preprocessed with an experimental scheme based on the CCG curve fitting routine to flag data that may be inappropriate for assimilation into models. All valid ECCC hourly averages are provided in this product; the curve-fitting scheme is used only to set obs_flag values in conjunction with the local time constraint.
  • NOAA tower insitu data are now additionally flagged if the calculated uncertainty (see Andrews et al., 2014) for a given observation exceeds 3ppm CO2.
  • The Digital Object Identifier (DOI) metadata for this product and required citation is at https://commons.datacite.org/doi.org/10.15138/G33W2G.

obspack_co2_1_GLOBALVIEWplus_v1.0_2015-07-30

This is the first major release of the GLOBALVIEWplus (GV+) cooperative data product. GV+ replaces ObsPack products called PROTOTYPE and is the next generation of the historic GLOBALVIEW products. The most significant difference between GV+ and earlier PROTOTYPE products is a nominal hourly time step for all high-frequency (quasi-continuous) measurements. In practice, this means the majority of original hourly data provided by PIs will simply be reformatted into the ObsPack framework. In some instances data sets include higher or lower time resolution as advised by the measurement PIs. Quasi-continuous records in PROTOTYPE products typically include a single value per day which is derived from a subset of hourly (or higher frequency) data identified by the contributing investigators as being representative of large well-mixed air masses. For example, in PROTOTYPE products, the reported value for each day from the NOAA in situ record at Mauna Loa, Hawaii (MLO) is derived when steady downslope wind conditions prevail (typically during nighttime). In GV+, all Mauna Loa hourly data are reported and values identified by the PI as being representative are assigned an ObsPack flag (obs_flag) value of one (1); all other hours are assigned an obs_flag value of zero (0). See ObsPack Documentation (Table 2) for details. One reason for this change is to accommodate the many high-frequency records where selection for large-scale representation is not based on time-of-day but on other criteria such as wind speed and direction, or measurements of radon and other tracers. In most instances, reporting a single value per day for these records does not make sense. As a result of this change, GV+ data set file names may differ from earlier PROTOTYPE products to indicate all valid or representative measurements are included. For example, the Mauna Loa record discussed above is called co2_mlo_surface-insitu_1_allvalid in GV+ and co2_mlo_surface-insitu_1_nighttime in earlier PROTOTYPE products.

There are significant differences between GLOBALVIEWplus and GLOBALVIEW products. Unlike GLOBALVIEW, GLOBALVIEWplus includes actual data provided by measurement PIs. Representative measurements as well as those that may be locally influenced are included and identified using the obs_flag variable (see ObsPack documentation for details). The historic GLOBALVIEW products are derived from measurements but do not include actual data. To facilitate use with carbon cycle modeling studies, the measurements have been selected by the measurement PIs for "baseline" conditions and processed by NOAA (smoothed, interpolated, and extrapolated) resulting in extended records that are evenly incremented in time. The gap-filling procedure used to prepare GLOBALVIEW products is based directly on measurements. A by-product of data extension methodology is a Marine Boundary Layer (MBL) reference matrix, which many researchers have found useful. Preparation of GLOBALVIEWplus does not require an MBL reference matrix, however, NOAA makes an improved MBL reference matrix freely available here.

This product also includes the following enhancements.

  • Includes 205 atmospheric carbon dioxide records derived from observations made by 25 laboratories from 16 countries. Data for the period 1968-2014 (where available) are included.
  • The Digital Object Identifer (DOI) metadata for this product and required citation is available here.
  • The 3-letter site identification code for Tierra del Fuego, Argentina (TDF) operated by NOAA was changed to USH to be consistent with the WMO GAWSIS.
  • The 3-letter site identification code for Schauinsland, Baden-Wuerttemberg, Germany (SCH) operated by UBA was changed to SSL to be consistent with the WMO GAWSIS.
  • The site map (metadata tag "site.map") has been replaced by a data set map (metadata tag "dataset.map"), which more accurately reflects the location of a unique sampling program. The file name format is map_<site code>_<project name>_<lab number>.png. For example, instead of a single map for all sampling projects at Park Falls, Wisconsin (LEF), we now include a map for each of the current projects at LEF, i.e., map_lef_aircraft-pfp_1.png,map_lef_surface-pfp_1.png, and map_lef_tower-insitu_1.png.
  • Logos, flags, and maps are now included in the "images" directory of this product.
  • The following metadata tags were renamed to more accurately reflect their meaning. See ObsPack Documentation for details.
    • "dataset_reference_total_listed" replaces "dataset_reference_number"
    • "lab_total_listed" replaces "lab_number". Similar changes were made for program, provider, and partner contributions.
    • "lab_#_number" replaces "lab_#_num" where # represents a number from 1 to "lab_total_listed". Similar changes were made for program and partner contributions (when partner is not an individual).
  • This product was prepared by Ken Masarie (NOAA) and Ingrid van der Laan-Luijkx (Wageningen University and ICOS-Carbon Portal).

obspack_co2_1_GLOBALVIEW-CO2

obspack_co2_1_GLOBALVIEW-CO2_2013_v1.0.4_2013-12-23

This package is GLOBALVIEW-CO2, 2013 presented in the ObsPack framework. The GLOBALVIEW-CO2, 2013 product includes a single extended data file per data record. Each file includes the extended record, the suggested relative weights assigned to each value, the reference marine boundary layer time series at the latitude of the sampling location, and extensive metadata.

The Reference Marine Boundary Layer matrix, which was provided in previous releases is no longer available. Instead, NOAA has made a more comprehensive MBL reference product available at http://gml.noaa.gov/ccgg/mbl/. Statistical summaries of key features in the observations are also no longer provided.

This update includes the following important changes.

  • The ObsPack Fair Use statement has been modified. Beginning November 2013, all new ObsPack data products will have a unique Digital Object Identifier (DOI) registered with the International DOI Foundation. In addition to the conditions of the ObsPack Fair Use statement, users must also include the ObsPack product citation in any publication or presentation using the product. The required citation is included in every data product file and in the automated e-mail sent to the user during product download. Also beginning November 2013, there are no longer any exceptions to this policy; it applies to all ObsPack products including GLOBALVIEW.

obspack_co2_1_GLOBALVIEW-CO2_2012_v1.0.3_2013-05-24

This revision corrects the following:

Surface elevation, intake height, and altitude were incorrectly reported in the extended aircraft text and netCDF files. In the ObsPack framework, we define altitude (masl) as surface elevation (masl) plus sample intake height (magl). In many aircraft records, surface elevation over which samples are collected is not always reported. In these cases, both surface elevation and intake height are assigned default values. Because GLOBALVIEW aircraft extended records are derived using altitude-binned time series, the reported altitude is the average of the altitude binning window.

We have removed unused ObsPack variables "value", "value_unc", and "nvalue" from the GLOBALVIEW data product. This was creating some confusion for users. Fields from the historic (pre-2012) GLOBALVIEW-CO2 text files have been more clearly labeled in this revision. "gv_utc", "gv_sc", "gv_ref", and "gv_diff" are from the historic extended (.ext) data text files and "gv_wt", "gv_wt_rsd", and "gv_wt_n" are from the weight (.wts) text files.

obspack_co2_1_GLOBALVIEW-CO2_2012_v1.0.2_2013-02-25

This revision introduces the global attribute "dataset_globalview_mbl_designation", which specifies whether or not the dataset was used in constructing the MBL reference matrix. A value of 1 means the data set was used to construct the MBL reference matrix; a value of 0 means the data set was not used. We have also added an EXCEPTION to the ObsPack Data Policy for GLOBALVIEW users (see below). The GLOBALVIEW data policy has not changed as of this time but will be reviewed at the GGMT-2013 meeting in June 2013.

"... EXCEPTION! If you download a GLOBALVIEW data product (any product with "GLOBALVIEW" in the product name), you are currently NOT required to contact GLOBALVIEW data providers. Please continue to reference GLOBALVIEW as you have in the past. We apologize for any confusion and will notify you if there are any changes to the GLOBALVIEW data policy."

obspack_co2_1_GLOBALVIEW-CO2_2012_v1.0.1_2013-01-04

This revision reassigns the variables used to present GLOBALVIEW results in the extended files. This reassignment does not affect the reported GLOBALVIEW results, only how they are presented. The variables, value, value_unc, and value_n will no longer be used in these files and are reserved for ObsPack data products that include actual data. Instead, GLOBALVIEW results are presented using the variables, gv_sc, gv_ref, gv_diff, gv_wt, gv_wt_rsd, and gv_wt_n. The extended records are constructed as before, i.e., gv_ref + gv_diff. Please note that default values have been changed to be consistent with other ObsPack products (i.e., -1e34 replaces -999.999 and -9 replaces -999). In addition, the list of AEMET data providers has been updated.

obspack_co2_1_GLOBALVIEW-CO2_2012_v1.0.0_2013-01-03

This package is GLOBALVIEW-CO2, 2012 reformatted into the ObsPack framework. The GLOBALVIEW-CO2, 2012 product includes a single extended data file per data record.
