This data file contains high accuracy European ObsPack observational timeseries in netCDF format of ambient mole fraction of 14CO2 in dry air collected at Observatoire pérenne de l'environnement (120.0 m). The measurements were calibrated using the WMO GAW calibration scale . 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 14CO2 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 14CO2 product release are available at https://commons.datacite.org/doi.org/10.18160/31ZQ-CXG0. Please also visit http://www.gml.noaa.gov/ccgg/obspack/ for more information. If you use these data in your research, please consider citing the full ObsPack release that this file is part of (https://commons.datacite.org/doi.org/10.18160/ERAF-JSPW).
