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
