The Institute of Meteorology and Climate Research - Department Troposphere Research (IMK-TRO) is part of the Institute of Meteorology and Climate Research (IMK). The IMK consists of four divisions, two of which are jointly operated by the Campus South (former University of Karlsruhe) and the Campus North (former Karlsruhe Research Centre). They work on atmospheric processes in the troposphere (IMK-TRO) as well as on atmospheric trace gases and remote sensing (IMK-ASF). A third division, the Atmospheric Aerosol Research (IMK-AAF) is jointly operated with the Institute of Environmental Physics at the University of Heidelberg. Since January 2002 the Institute for Atmospheric Environmental Research, former part of the Fraunhofer Gesellschaft, has become the fourth division of the IMK as IMK-IFU.
The Institute is leading the newly founded KIT "Climate and Environment" Center and contributes significantly to the program "Atmosphere and Climate" of the Helmholtz Association in the research field "Earth and Environment".
The teachers of the university offer courses for Meteorology (bachelor, master and diploma).
