CLIMGAS-CH (HALCLIM) / AGAGE: Continuous measurements of halogenated greenhouse gases at the high Alpine site of Jungfraujoch for identification of trends and regional European emissions.

CO₂, CH₄, N₂O and CO: Next to the halogenated greenhouse gases and ozone-depleting substances, also the important greenhouse gases carbon dioxide (CO₂), methane (CH₄), nitrous oxide (N₂O) and carbon monoxide (CO) greenhouse gases are continuously measured at Jungfraujoch.

NABEL_VOCs: Continuous measurements of volatile organic compounds (VOCs) at the NABEL sites of Zürich (urban), Dübendorf (suburban), Rigi (rural) and Jungfraujoch (high Alpine, background).

 

ACTRIS-2 is the European Research Infrastructure for the observation of Aerosol, Clouds, and Trace gases. ACTRIS-2 is composed of observing stations, exploratory platforms, instruments calibration centres, and a data centre.

WP3: Near-surface observations of aerosols, clouds and trace gases
The overall objective of this work package is to consolidate and optimize the European capabilities to observe near-surface-based climate and air quality relevant properties of aerosol particles, cloud droplets as well as trace gases concentrations in the troposphere from ground-based stations.
