Group for Climate Gases

The main activities of the Group for Climate Gases are centered around the observations of anthropogenic trace gases in the atmosphere. Data is exploited for detection of sources and sinks of these gases as well as trends and their influence on atmospheric chemistry.

Trace Gas Measurements at Jungfraujoch

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

NABEL CH4 / N2O / SF6 / CO: Continuous measurements of methane (CH4), nitrous oxide (N2O), sulfur hexafluoride (SF6) and carbon monoxide (CO) as non-CO2 greenhouse gases at the high Alpine site of Jungfraujoch for identification of trends and regional European emissions.

 

 

Halogenated greenhouse gases

AGAGE: Continuous measurements of halogenated greenhouse gases at the high Alpine site of Jungfraujoch for identification of trends and regional European emissions.

SOGE-A: System for Observations of Greenhouse Gases in Europe and Asia.

Mehal-GG: First-time top down estimation of halocarbon emissions for Southeastern Europe and the Iberian Peninsula, based on atmospheric measurement campaigns in Finokalía (Crete, Greece) and  Pic du Midi (Pyrenees, France).

 

 

Volatile organic compounds

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 work package 4: The term gaseous precursors of secondary air pollutants comprise a wide range of chemical species and reactivities. Precursors (i.e. primary pollutants) are emitted either by anthropogenic or biogenic sources, with the volatile organic compounds (VOCs) and the nitrogen oxides (NOxy) as main groups. Important secondary air pollutants produced from these precursors are ozone (O3), secondary organic aerosols (SOA) and nitrates. (ACTRIS WP 4 web)

Hydrogen

Molecular hydrogen (H2) is one of the most abundant trace gases in the atmosphere with a globally averaged mixing ratio of approximately 530 ppb. However, limited attention has been paid to the sources and sinks as well as the role that H2 plays in atmospheric chemistry. Nevertheless, H2 has recently become a trace gas of wider scientific interest mostly due to the ongoing discussion on switching our fossil-fuel based economy to a hydrogen-based economy.
