This data file contains high accuracy European ObsPack observational timeseries in netCDF format of ambient mole fraction of CO in dry air collected at Hyytiälä (67.2 m). The measurements were calibrated using the WMO GAW calibration scale WMO X2014A. 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 2026.2 FastTrack update of the Globalview EU data product and is intended for use in carbon cycle inverse modeling, model evaluation, and satellite validation studies. Metadata for the full CO product release are available at https://commons.datacite.org/doi.org/10.18160/00CE-F550. 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/10.18160/1PZ9-SDJ2).
