AB  - Atmospheric Greenhouse Gas Mole Fractions of CO2, CH4 and N2O collected in Europe, covering the period 1972-2026 for CO2, 1984-2026 for CH4, and 1994-2026 for N2O, including final quality-controlled Level 2 ICOS data, release L2-2026.1. During the most recent period, a selected set of stations, after being labelled as ICOS stations, follow the ICOS Atmospheric Station specification V1.3. All concentrations are calibrated to the WMO X2019 CO2 mole fraction scale in µmole/mole (ppm), WMO X2004A CH4 mole fraction scale in nmole/mole (ppb) and WMO X2006A N2O mole fraction scale in nmole/mole (ppb).
