the Cryosphere and Atmospheric Chemistry (CATCH)

Emerging IGAC Activity on Chemistry, Biology and Physics in Cold Regions

CATCH is jointly sponsored by: 


NOW Accepting Nominations for the 2018 CATCH Steering Committee
Deadline 31 October 2017

CATCH is accepting nomination for its steering committee.  The steering committee will replace the current implementation committee in order to move the CATCH activity forward starting in January 2018.  CATCH aims to have a balance across disciplines (physics, chemistry, biology), geographical regions, gender, and career levels on its steering committee. Self nominations are welcome.

The CATCH mission is to facilitate atmospheric chemistry research within the international community, with a focus on natural processes specific to cold regions of the Earth. Cold regions include areas which are seasonally or permanently covered by snow and ice, from the high mountains to the polar ice sheets and sea ice zones as well as regions where ice clouds that undergo chemistry are found.

CATCH scientists will aim to understand and predict:

  • How aerosols are formed and processed in cold regions;
  • How cold region aerosols act as and impact cloud properties;
  • Feedbacks between climate change and atmospheric chemistry that are determined by changes in the cryosphere;
  • How the ice core record can be used to understand global environmental change;
  • How physical, chemical, biological, and ecological changes in sea ice and snow impact atmospheric chemistry;
  • How microbiology adapts and impacts biogeochemical cycling of elements in ecosystems of cold environments; and
  • Establish background composition (trace gases and aerosols) in cold regions that are undergoing industrialization as well as impacted by climate change.
