    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. Please visit http://www.esrl.noaa.gov/gmd/ccgg/globalview/co2/co2_whatsnew.html to see what is new in this update.

    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.

    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.

  • 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 (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_CARBONTRACKER_CT2013_2014-05-08

    This product is a combination of an ObsPack Data Product and CarbonTracker simulated data. CarbonTracker data are variables starting with 'model_'. The observations simulated in CT2013 came from parts of multiple ObsPacks. This product is a compilation of data from those multiple products to provide a convenient single product that includes a contiguous record of those observations and their simulated values. An ObsPack Data Product is a compilation of atmospheric greenhouse gas data and metadata records produced by one or more national or university laboratories and prepared for distribution using the ObsPack framework. An ObsPack Data Product is NOT intended to be a primary source of actual data nor is it intended to include all measurement documentation. If you are interested in actual data or would like more comprehensive documentation on the measurements, please contact the data provider directly. 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 ObsPack contact. Please read carefully the ObsPack Fair Use statement and cite appropriately. Please visit http://www.esrl.noaa.gov/gmd/ccgg/obspack/ for more information.

    The data provided here are intended to be a record of the observations simulated in CT2013. Generally, we recommend that users not use these data but instead download the latest ObsPack PROTOTYPE product, which contains not only more recent data, but also incorporates any corrections subsequently supplied by the data providers. Please visithttp://www.esrl.noaa.gov/gmd/ccgg/obspack/ to download the most recent data. Every effort is made to create the most accurate and precise data product possible. Contributors reserve the right to make corrections to this product and data based on recalibration of standard gases or for other reasons deemed scientifically justified.
