The new dataset of atmospheric observations of greenhouse gases by the Research Infrastructure ICOS (Integrated Carbon Observation System) has been released for the period September 2015 - January 2021. This dataset contains the observations of 26 stations in Europe, including the Monte Cimone class-2 site managed by CNR-ISAC in collaboration with the Air Force - CAMM of Monte Cimone. The dataset contains the hourly average values of CO2, CH4, N2O, CO and the meteorological variables observed at the ICOS atmospheric sites. For a subset of measurement sites, 14C in CO2 is also available. All stations follow the ICOS Atmospheric Station specification V2.0 (doi: 10.18160 / GK28-2188) together with a common data processing strategy (see Hazan et al. 2016; doi: 10.5194 / amt-9-4719-2016).
