GreenHouse Gases Concentration - ICOS Level 1 and Level 2 data

Measurement of atmospheric concentration of greenhouse gases (carbon dioxide, methane) performed in compliance with ICOS protocols established for class-2 atmospheric stations (https://www.icos-cp.eu/about/join-icos/process-stations#toc-station-classes-class-1-class-2-associated-stations). Measurements are performed at the ICOS class-2 atmosphere station in Ispra (building 77r). This station is a component of the European Commission Atmospheric Observatory.
Near Real-Time (NRT) measurements are Level 1 ICOS data that are not fully quality checked. NRT data is a growing time series starting from the last ICOS data release of Level 2 data, that is from 01/04/2024. Level 2 data are fully quality checked measurements starting from 15/12/2017 till 31/03/2025.
