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.
The IMK-AAF

  • 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.

Ice nucleation by cellulose aerosol

Searching for the ice nucleating particle (INP) types in the atmosheric aerosol is still a major challenge of aerosol-cloud-climate research. Scientists from the Karlsruhe Institute of Technology, the Meteorological Research Institute in Tsukuba, Japan, and the University of Bielefeld have identified cellulose as an important source of atmospheric INPs, as reported  in Nature Geoscience 8, 273-277 (2015) .

International Symposium on Ultrafine Particles

The effects of ultrafine particles, the smallest constituents of airborne particulate matter, on air quality, atmospheric processes, climate, and human health are by far not finally investigated to proven evidence. The 5th EFCA Ultrafine Particles Symposium  will reflect the most recent scientific progress in the field and aims to contribute to the dialogue with policymakers in Europe.  The symposium takes place on May 4 - 5 in Brussels, Belgium. It is co-organized by KIT and chaired by the head of IMK-AAF, Prof. Thomas Leisner.

 
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
