Description (Abstract)

2026-1 release containing data from the atmospheric network of ICOS Research Infrastructure for 41 stations and atmospheric composition at all available vertical levels at stations El Arenosillo, Birkenes, Cabauw, Monte Cimone, Gartow, Helgoland, Hohenpeissenberg, Hyltemossa, Hegyhátsál háttérszennyettség-mérő állomás, Ispra, Izaña, Jungfraujoch, Jülich, Karlsruhe, Křešín u Pacova, Lindenberg, Lampedusa, Lutjewad, Mace Head, Norunda, Observatoire pérenne de l'environnement, Ochsenkopf, Pallas, Plateau Rosa, Puijo, Puy de Dôme, Ridge Hill, La Réunion, Saclay, Hyytiälä, Station Nord, Schauinsland, Steinkimmen, Svartberget, Torfhaus, Trainou, Utö - Baltic sea, Weybourne, Westerland, Zeppelin and Zugspitze. This collection contains the final quality controlled hourly averaged data for the mole fractions of CO2, CH4, N2O, CO, activity concentrations of Radon-222 and meteorological observations measured at the relevant vertical levels of the measurements stations; 14C in CO2 in two-weekly integrated samples (18 stations); and analysed flask data for CO2, CH4, CO, N2O, SF6, H2, delta18OCO2, delta O2N and 14C (19 stations), for the period September 2015-1 April 2026. All stations follow the ICOS Atmospheric Station specification V2.0 (https://doi.org/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).
