Obspack CO time-series result from Norunda (100.0 m), 2017-04-01–2026-08-05

This data file contains high accuracy European ObsPack observational timeseries in netCDF format of ambient mole fraction of CO in dry air collected at Norunda (100.0 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 CO European Obspack data product (version 12.0) and is intended for use in carbon cycle inverse modeling, model evaluation, and satellite validation studies.
