ICOS Atmosphere Release 2022-1 of Level 2 Greenhouse Gas Mole Fractions of CO₂, CH₄, N₂O, CO, meteorology and ¹⁴CO2

This 2022-1 release containing data from the atmospheric network of ICOS Research Infrastructure for 36 stations and 90 vertical levels at Birkenes, Gartow, Helgoland, Hohenpeißenberg, Hyltemossa, Ispra, Jungfraujoch, Jülich, Karlsruhe, Křešín u Pacova, La Réunion, Lampedusa, Lindenberg, Lutjewad, Monte Cimone, Norunda, OPE, Ochsenkopf, Pallas, Plateau Rosa, Puijo, Puy de Dôme, La Réunion, Ridge Hill, Saclay, SMEAR-II Hyytiälä, Station Nord, Schauinsland, Steinkimmen, Svartberget, Torfhaus, Trainou, Utö - Baltic Sea, Westerland, Weybourne and Zeppelin Observatory. This collection contains the final quality controlled hourly averaged data for the mole fractions of CO₂, CH₄, N₂O, CO and meteorological observations measured at the relevant vertical levels of the measurements stations, and where available ¹⁴C in CO₂ in two-weekly integrated samples, for the period September 2015-February 2022. All stations follow the ICOS Atmospheric Station specification V2.0 (doi:10.18160/GK28-2188) and are certified as ICOS atmospheric stations Class I or II. Data processing has been performed as described in Hazan et al., 2016 (doi:10.5194/amt-9-4719-2016).
