This is the 2021-2 INTERIM release of the ICOS final quality ecosystem data product that includes eddy covariance fluxes, meteorological observations, ancillary and biometric data and full metadata at 15 labelled ICOS stations in the ecosystem domain. The archives contain more detailed description of the different data files contained in the archives. Please note that the 2021 measurements don't cover the full year, but do essentially cover the growing season. Measurements have been collected using the following instructions:
