This data file contains high accuracy European ObsPack observational timeseries in netCDF format of ambient mole fraction of ch4 in dry air collected at Saclay (100.0 m). The measurements were calibrated using the WMO GAW calibration scale WMO X2004A. 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 2025.3 FastTrack update of the Globalview EU CH4 data product and is intended for use in carbon cycle inverse modeling, model evaluation, and satellite validation studies. Metadata for the full ch4 product release are available at https://commons.datacite.org/doi.org/10.18160/3TB5-D6TM. Please also visit http://www.gml.noaa.gov/ccgg/obspack/ for more information.
