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

New DFG funded research on brown carbon

In October 2021, Dr. Stephanie Jones started at the IMK-AAF after having successfully obtained DFG funding for her own position. Her research will investigate the transformations of brown carbon aerosol using single droplet levitation techniques and cloud chamber experiments.

Ice-nucleating particle measurements at Storm Peak Laboratory (CO, USA)

Since October 2021, PINE monitors ice-nucleating particle concentrations in the Rocky Mountains. Being located at 3200 m a.s.l., the site frequently provides free-tropospheric sampling conditions in an atmospheric layer where mixed-phase clouds occur.

AIDArct: simulating Arctic atmospheric conditions in the AIDA chamber

The AIDArct experiment will reproduce Arctic atmospheric conditions in the AIDA chamber with the goal of parametrizing the effects of atmospheric transport on absorption and hygroscopicity of black carbon particles.

Quantifying ice-nucleating particles in Iceland’s desert

IMK-AAF contributed to field experiments in Iceland to investigate the mineral composition of Icelandic dust and its effects on climate. In the desert of Dyngjusandur/ Iceland airborne dust for ice nucleation experiments was collected.

Better forecasts for air quality, weather and climate - Funding of ACTRIS-D

The German Federal Ministry of Education and Research (BMBF) supports the development of the new research infrastructure ACTRIS-D. KIT will receive about 14 million Euros to establish new measurement facilities for cloud research, to significantly expand existing infrastructures and to equip them with state-of-the-art measurement technology.
