Aerosols, Clouds, and Atmospheric Chemistry

Welcome to the division "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 field campaigns
  • performs numerical modelling of atmospheric aerosol processes

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



KIT GRACE student contributes to FIN03

During September 2015, U.S. and German teams of atmospheric ice nucleation research collaborate at the Storm Peak Laboratory, Steamboat Springs, Colorado, to intercompare methods for sampling ice nucleating particles from ambient air. This activity called FIN03 is the final major experimental activity within the Fifth International Ice Nucleation Workshop (FIN). The KIT PhD student Thea Schiebel is participating in this activity as part of her 3 month visit to the Colorado State University which is supported by the KIT Graduate School for Climate and Environment (GRACE) 

The Fifth International Ice Nucleation Workshop (FIN)

This workshop is the most comprehensive ever held concerning atmospheric ice nucleation studies. Three phases include intercomparison of single particle mass spectrometers (FIN01, Nov 2014) and of ice nucleation measurement methods (FIN02, Mar 2015), both held at the KIT AIDA cloud chamber, and intercomparison of methods for sampling ice nucleating particles from ambient air at Storm Peak Laboratory, Steamboat Springs (FIN03, Sep 2015). The FIN activities are supported by NSF, DOE-ASR and DFG (Research Unit INUIT).

Research Infrastructure Project AIDA-2

The ongoing AIDA-2 project includes the construction of a new lab building, the renovation of the AIDA facility, the installation of an aerosol mass spectrometry lab, and the construction of a novel dynamic cloud chamber. Building construction and AIDA renovation are making good progress. Reopening of the AIDA facility is planned for September after the installation of a new liquid gas supply system.

Aerosol Simulation Web Site Released by IMK-AAF A web based version of the extensively validated detailed numerical aerosol process model COSIMA-F has been made freely available to the public. This code describes the structural properties and dynamical evolution of  ramified aggregates, e.g. freshly emitted soot, based on fractal scaling laws. However, it can also be operated like a conventional aerosol behaviour code when dealing with compact aerosol particles. Several entirely editable default scenarios are available. For more information or conducting your own simulations please visit the COSIMA homepage
