This data file contains high accuracy European ObsPack observational timeseries in netCDF format of ambient mole fraction of CH4 in dry air collected at Křešín u Pacova (125.0 m). The measurements were calibrated using the WMO GAW calibration scale WMO CH4 X2004A. Included are (all whenever available) historical PI QCed data, ICOS Level 2 data and ICOS NRT data. It is part of the CH4 European Obspack data product (version 11.0) 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/X5ZG-C3WE. 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).
