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.



6th Staubtag Meeting

On November 18 and 19, 2019, scientists from different fields of research on the subject of mineral dust came together for the 6th time now. The meeting was initiated six years ago to promote the exchange of current questions and research results between the research fields, to discuss new ideas and to establish interdisciplinary contacts (http://www.tropos.de/aktuelles/veranstaltungen/leipziger-staubtag/).

This year, 40 international scientists met at KIT to present short lectures and posters about their work on the emission of mineral dust and its meteorological prediction, on the interaction of natural desert dusts with anthropogenic impurities and on the reduction of the efficiency of photovoltaic systems by high atmospheric dust concentrations.

Next year the Staubtag Meeting will take place in Munich.

Actris-European Research Infrastructure / climate research
Germany expands climate research activities

The German Federal Ministry of Education and Research decided to substantially support ACTRIS-D as one of three infrastructures recently selected for the National Roadmap on the installation of research infrastructures. ACTRIS-D is the German Consortium of the European Research Infrastructure for the observation and investigation of Aerosols, Clouds and Trace Gases (ACTRIS). By the long-term observations, research activities and infrastructure services, ACTRIS will substantially contribute to develop more robust and reliable predictions for climate, weather and air quality.

ACTRIS-D will be coordinated by TROPOS (Leibniz-Institut für Troposphärenforschung) in Leipzig. IMK-AAF will coordinate the implementation and operation of the topical centre for Cloud In Situ Measurements (CIS). Further partners of CIS are the University of Manchester, the Leibniz Institute for Tropospheric Research (TROPOS) and the Zentralanstalt für Meteorologie und Geodynamik (ZAMG), Austria.

First MOSES campaign on heat waves near Jülich

MOSES is a novel flexible observing system of the Helmholtz Association specifically designed to investigate the interactions of short-term events and long-term trends. The events in focus are heat waves, hydrological extremes, ocean eddies and permafrost thaw. A first measurement campaign on heat waves took place in July 2018 near Jülich studiing soil moisture, ground - atmosphere exchange processes, and the distribution of atmospheric aerosol particles. Focus of our contribution was the determination of aerosol particle and cloud spatial distributions using a new 3D scanning aerosol LIDAR. This work will improve our understanding how aerosols, extrem weather, and climate change interact.

Bolivia campaign – particle nucleation and urban influence at 5240 masl

Aerosol particle nucleation and urban influences are studied at the Chacaltaya GAW Station (CHC) in the Bolivian Andes (16°21.014'S, 68º07.886'W, 5240 masl). The Chacaltaya mountain directly faces a plateau of 3800 masl in the south and west and is separated from the Amazon basin by higher peaks in the north and east. Research groups from La Paz, Stockholm, Helsinki, Innsbruck, Granada, Leipzig, and Karlsruhe combine their instruments to characterize the aerosol from November 2017 to June 2018. Focus of our contribution is the molecular composition of gas- and particle phase on the mountain and in the La Paz – El Alto metropolitan area.
