This data package contains high accuracy CH4 dry air mole fractions from 68 ICOS and non-ICOS European observatories at in total 150 observation levels, collected by the ICOS Atmosphere Thematic Centre (ATC) and provided by the station contributors. The package is the 2025 update of the European Obspack data product (version 11.0), released in 2025 and is intended for use in carbon cycle inverse modeling, model evaluation, and satellite validation studies. Please report errors and send comments regarding this product to the ObsPack originators. Please read carefully the ObsPack Fair Use statement and cite appropriately. Metadata for this product are available at https://commons.datacite.org/doi.org/10.18160/X5ZG-C3WE. Please visit http://www.gml.noaa.gov/ccgg/obspack/ for more information.
