Institute for Atmospheric and Climate Science


The institute consists of six research groups.

The Climate Physics group, led by Prof. Reto Knutti, has its focus on modelling the global coupled climate system. The group has strong interests in constraining climate feedbacks by comparing models with observations, and in methods to quantify expected future climate change and its uncertainty resulting from anthropogenic forcing. The group maintains several models to simulate climate change scenarios on decadal to millenial time scales.
The Atmospheric Physics group, led by Prof. Ulrike Lohmann, focuses on aerosol-cloud interactions in warm, mixed phase and ice clouds and their importance for the radiation budget and the hydrological cycle. It develops instrumentation and observation methods, applying these to aerosol and cloud microphysics in field experiments and in the laboratory. It maintains a suite of numerical models ranging from Lagrangian air parcel models over regional models to global climate models. Finally, the groups deals with some physical aspects of biometeorology.
The Atmospheric Chemistry group, led by Prof. Thomas Peter, deals with modern aspects of tropospheric and stratospheric chemistry, with a strong focus on cloud and aerosol microphysics, heterogeneous chemistry, and cloud radiation interaction. It also has the scientific surveillance of the renowned ozone time series of Arosa and Payerne. Investigations are performed by means of laboratory experiments, field measurements, as well as by theoretical and modeling studies.
The Climate and Water Cycle group, led by Prof. Christoph Schär, is concerned with atmospheric and hydrological processes relevant to weather and climate on the scale of the European continent and the Alps. The group maintains a regional climate model, several atmospheric and hydrological models, and a comprehensive data set of Alpine precipitation.
The Land-Climate Dynamics group, led by Prof. Sonia Seneviratne, investigates the role of land feedbacks and processes in the global and regional climate systems. It focuses in particular on the analysis of impacts of land-climate interactions on extreme events, climate variability and climate change, the evaluation of land-atmosphere coupling characteristics in models and observations, and the development of new observations-based datasets.
The Amospheric Dynamics group, led by Prof. Heini Wernli, concerns itself with the modeling, diagnostic analysis, and theory of weather systems and atmospheric transport processes. The group develops and maintains a suite of diagnostic tools and numerical models ranging from idealized research models to complex weather forecasting models. It also starts to perform measurements of stable water isotopes with high temporal resolution.
