Location: How to find us


The Institute of Atmosphere and Climate Science (IAC) focuses on atmospheric and climate processes, including links to the hydrosphere, cryosphere, and biosphere. Research is directed at understanding how human activities alter these processes via changes in greenhouse gases, aerosols, chemical constituents, and land surfaces and how this impacts upon climate, ozone, UV radiation, pollutant exposure, ecosystems, water resources and extreme events. Emphasisis placed on the improvement of the predictive capabilities on weather and climate time scales and on knowledge transfer between basic sciences, applied sciences, and society. See our Research Focus page for more information.

The research of the institute is linked to several national and international projects and organizations, among these the Center for Climate Systems Modeling (C2SM).


The IAC is involved in the education within the curriculum of several within the ETH departments, especially of the Department of Environmental Systems Science (D-USYS) and the Department of Earth Sciences (D-ERDW). IACETH provides lecture courses, practicals and seminars.
