The Department of Atmospheric and Cryospheric Sciences (ACINN) is one of the few university departments worldwide where research and education in atmospheric science and glaciology are co-located. Accordingly, ACINN's research focus lies on aspects of mountain meteorology, earth-atmosphere interaction - with a focus on snow- or ice-covered surfaces, exchange of gases and aerosols at the surface, exchange over complex topography - and ice-climate relations.

The ACINN is devoted to basic research in the areas of weather forecasting, mountain meteorology, atmospheric composition, earth atmosphere interactions and ice-climate relations. Our research activity is largely supported by third-party funding. We investigate the atmosphere, the biosphere and the cryosphere – and their interactions – through theoretical/conceptional approaches, experimental means and numerical modeling.
Detailed information on specific research themes can be found for each of the Research Units. 

ACINN is embedded in the university's research areas Alpine Space - Man and Environment and Scientific Computing. It plays a key role in the research centre Climate: Cryosphere and Atmosphere. Bachelor and Master programs in Atmospheric Sciences have a strong focus on weather forecast, again of course with a special emphasis on mountain weather and climate.
