Welcome to the Institute for Meteorology and Climate Research - Troposphere Research (IMK-TRO). 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.
