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

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.

PINE monitors ice-nucleating particles at the Košetice Observatory (CZ)

End of April 2021, the mobile cloud expansion experiment PINE started a two months period for continuous measurements of ice-nucleating particles (INPs) at the Košetice National Atmospheric Observatory in the Czech Republic.

Virtual Access to the AIDA facility

Many scientists from around the world have used the opportunity to virtually access the AIDA facility to do measurement campaigns in close collaboration with the local team. These activities are supported by the EU projects EUROCHAMP2020 and ATMO-ACCESS and allow use of the facility even if travelling is not possible.
