April 2026 complete collection of atmospheric Greenhouse Gas Mole Fractions of CO2, CH4, N2O and CO in Obspack netcdf format collected by the ICOS ATC, covering the period 1972-2026, including historical PI quality checked data (marked as level 0), final quality-controlled Level 2 ICOS data release 2025-1 (marked as level 2), FastTrack 2026.2 ICOS data (marked as level 1.5) and NRT ICOS data (marked as level 1) up to 10 April 2026. The set contains data for up to 40 ICOS stations and max 98 observation levels. During the most recent period, after being labelled as ICOS stations, observations from ICOS stations follow the ICOS Atmospheric Station specification V2.0. The measurement and data processing for all time series is described in Ramonet et al., 2020. All observations are calibrated against the respective current WMO mole fraction calibration scales (WMO CO2 X2019, WMO CH4 X2004A, WMO N2O X2006A, WMO CO X2014A).
