Paris, France

The Community workshop on Cryospheric Atmospheric Chemistry Activity (CATCH) will be held from 19-21 April 2017 in Paris, France.


11 Boulevard d'Alembert
78280 Guyancourt, France
Nearest train station: Saint-Quentin-en-Yvelines (local trains from Paris)


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 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 cloud precursors and impact cloud properties?
- What are the feedbacks between climate change and atmospheric chemistry that are deter­mined by changes in the cryosphere?
- How the ice core record can be used to understanding global environmental change?
- How physical, chemical, biological, and environmental change ecological changes in sea ice and snow impact atmospheric chemistry?

Moreover, CATCH aims to establish the background composition (trace gases and aerosols) in cold regions that are undergoing industrialisation, as well as being impacted by climate change.
