Atmospheric processes
The Atmospheric Processes Group was installed in October 2003 and is currently headed by Professor Hans-F. Graf.
Research is mainly based on numerical modelling of physico-chemical processes in the climate system and data analysis.
Topics range from aerosols in the upper troposphere/lower stratosphere (PARTS), the dynamic coupling between troposphere and stratosphere (KODYACS) to effects of smoke from biomass burning on clouds and atmospheric chemistry (SMOCC, EFEU, INSIDE) and exchange of water and other chemicals relevant for stratospheric ozone between troposphere and stratosphere (SCOUT).
Recent results include the development of a 
Convective Cloud Field Model based on principles of self-organization for use in global climate models, and a new approach to coupled stratosphere-troposphere-ocean coupling. The high resolution plume model ATHAM, used for volcanic eruptions, biomass burning plumes and deep convective clouds, plays a central role in model development of the group.
