Atmospheric Aerosol Research (IMK-AAF)

Welcome to the department "Atmospheric Aerosol Research" of the Institute of Meteorology and Climate Research, Karlsruhe Institute of Technology. Our research focuses on the role of aerosols in the climate system, the hydrological cycle, and the environment.

  • operates the internationally renowned AIDA aerosol and cloud simulation chamber
  • runs laboratories for aerosol and cloud research
  • participates in ground-based and aircraft field campaigns around the world

The head of the division, Thomas Leisner, is professor at the Institute of Environmental Physics, University of Heidelberg

Cloud droplets under pressure

The pressure in freezing cloud droplets rises until the ice shell cracks. These repetitive cracks are the source for small ice splinters which in turn may freeze further cloud droplets. With the help of thermography, internal pressures up to 170 bar could be detected.

ATMO-ACCESS develops a new framework for access to atmospheric research infrastructures

ATMO-ACCESS is a new infrastructure project funded by the European Commission after application the INFRAIA-03-2020 call. The project will develop a new framework for access to distributed atmospheric Research Infrastructures. Among these infrastructures is the AIDA cloud simulation chamber of KIT.
