obspack_co2_1_PROTOTYPE_v1.0.3_2013-01-29

This is a minor revision to the obspack_co2_1_PROTOTYPE_v1.0.x data product. This update includes the following changes.

• This revision restores the inclusion of NOAA data through 2012-04-30.

obspack_co2_1_PROTOTYPE_v1.0.2_2013-01-28

This is a minor revision to the obspack_co2_1_PROTOTYPE_v1.0.x data product. This update includes the following changes.

• The latitude of NOAA samples collected at Ascension Island (ASC) was incorrectly reported as 7.9667N. The correct latitude is 7.9667S. This error DID NOT OCCUR in revisions prior to v1.0.1. We have introduced an additional QC procedure to help us ensure sampling coordinate errors are identified and fixed prior to a product release.

obspack_co2_1_PROTOTYPE_v1.0.1_2012-12-10

This is a minor revision to the obspack_co2_1_PROTOTYPE_v1.0.x data product. This update includes the following changes.

• The latitude of the Sable Island, Nova Scotia, Canada (WSA) sampling location was incorrectly reported as 49.9333N. The correct value is 43.9333N.
• Erroneous July and August 2011 measurements included in the Lac Labiche, Alberta, Canada (LLB) in situ record operated by Environment Canada (EC) have been corrected.
• A problem was identified and corrected in the October 2010 measurements from Storm Peak Laboratory, Colorado, United States (SPL) operated by the National Center For Atmospheric Research (NCAR).
• Includes an additional quasi-continuous record from Pallas-Sammaltunturi, Finland (PAL) prepared by the Finnish Meteorological Institute (FMI). This new record "co2_pal_surface-insitu_30_nonlocal" has been selected to include non-local influences determined by evaluating hourly data where the hourly standard deviation <3 ppb and wind speed >3.0 m/s during June-August and >4.0 m/s otherwise.
• Includes measurements from the NOAA surface flask network at 1) Maxaranguape, Brazil (NAT) in cooperation with Instituto de Pesquisas Energticas e Nucleares (IPEN) and 2) the Centro de Investigacion de la Baja Atmosfera,Spain (CIB) in cooperation with the Centro de Investigacion de la Baja Atmosfera (CIBA).

obspack_co2_1_PROTOTYPE_v1.0.0_2012-11-05

This is a major revision to the obspack_co2_1_PROTOTYPE data product. This update includes the following changes.

• Includes quasi-continuous insitu aircraft measuremetnts from the HIPPO campaign (HIP) coordinated by Harvard University (HU).

• Includes measurements from the Japan Meteorological Agency (JMA) surface insitu network (MNM, RYO, YON).
• Includes measurements from the NOAA shipboard sampling in the Drake Passage (DRP).
• Re-describes mobile shipboard data from the NOAA surface network (POC, SCS, DRP) as "shipboard-flask" data.

obspack_co2_1_PROTOTYPE_v0.9.5_2012-09-19

This is a minor revision to the obspack_co2_1_PROTOTYPE_v0.9.x data product. This update includes the following changes.

• Improves the readability of data set names by replacing dataset_num with selection_tag (e.g., co2_wkt_tower-insitu_1_110 becomes co2_wkt_tower-insitu_1_afternoon-457magl)
• Redefines several global attributes and variable names to improve understanding and usage.

obspack_co2_1_PROTOTYPE_v0.9.4_2012-09-06

This is a minor revision to the obspack_co2_1_PROTOTYPE_v0.9.x data product. This update includes the following changes.

• Introduces a 'lookup' text file that relates each unique ObsPack data item number to the data file in which the data item resides. This file is also available as a configuration (rc) file.

obspack_co2_1_PROTOTYPE_v0.9.3_2012-08-24

This is a minor revision to the obspack_co2_1_PROTOTYPE_v0.9.x data product. This update includes the following changes.

• Corrects several problems identified in the previous release.
• Quasi-continuous data from Alert (ALT) provided by Environment Canada are now included.
• NOAA surface shipboard measurements from POC are now included.
• NOAA surface in situ records from BRW, MLO, SMO, and SPO now include data beginning 2000.
• Errors in the metadata describing the NIES-MRI CONTRAIL data (CON) have been corrected. The CON record now includes data beginning 2000.
• We have expanded the use of a data set selection variable that provides a very brief escription (a general impression really) of how providers have selected their data for use in this product. In some instances, data have not been selected other than to flag and exclude values with known experimental problems. Data selection terms include 'all valid measurements', 'representative of site', 'afternoon hours', 'nighttime hours', filtered daily average', 'marine', 'continental', 'global', 'regional', and 'local'. The meaning of these terms may vary between laboratories. For more information, please contact the data providers or review the included references in each data set.

obspack_co2_1_PROTOTYPE_v0.9.1_2012-07-24

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 (see www.esrl.noaa.gov/gmd/ccgg/globalview/co2/co2_citation.html for details). 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. 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://www.esrl.noaa.gov/gmd/ccgg/mbl/. Statistical summaries of key features in the observations are also no longer provided. Please see http://www.esrl.noaa.gov/gmd/ccgg/globalview/ for comprehensive GLOBALVIEW-CO2 documentation.

obspack_co2_1_GLOBALVIEW-CO2_v1.0_2012-07-25

This package contains extended records from GLOBALVIEW-CO2, 2011 reformatted into the ObsPack framework. For the full GLOBALVIEW-CO2, 2011 release please visit http://www.esrl.noaa.gov/gmd/ccgg/globalview/.
