In the field of tropospheric research, fundamental research on climate, water cycle and trace gas budgets are carried out. These atmospheric processes such as turbulence, convection, cloud formation, aerosol physics, precipitation formation and exchange processes on the Earth's surface by measurements and theoretical methods are examined in detail. The results are used in models of the atmosphere to represent and predict processes in the climate system or weather phenomena.
IMK-TRO is organized in working groups that cooperate closely with IMK-ASF, IMK-AAF, and IMK-IFU, other Helmholtz-Centers, Institutes at University of Karlsruhe as well as other national and international research institutes. These working groups use newest measurement techniques, partly developed by the IMK, in larger experiments. At the same time numerical weather prediction models are developed and applied.
