This data file contains high accuracy European ObsPack observational timeseries in netCDF format of ambient mole fraction of CO2 in dry air collected at Cabauw (27.0 m). The measurements were calibrated using the WMO GAW calibration scale WMO CO2 X2019. Included are (all whenever available) historical PI QCed data, ICOS Level 2 data, ICOS FastTrack data and ICOS NRT data. It is part of the CO2 European Obspack data product (version 12.0) and is intended for use in carbon cycle inverse modeling, model evaluation, and satellite validation studies. Metadata for the full CO2 product release are available at https://commons.datacite.org/doi.org/10.18160/05HT-73FW. Please also visit http://www.gml.noaa.gov/ccgg/obspack/ for more information.
