Analysis of large atmospheric and hydrological data sets is an ongoing challenge in our research field.

Climate Physics Group

Prof. Reto Knutti

Big data sets of numerous global and regional climate models are used to study the changes in the global climate system caused by the growing emissions of anthropogenic greenhouse gases such as carbon dioxide.

Prof. Ulrike Lohmann

Two-dimensional images of single cloud particles are algorithmically detected by analysing large amount of image data.

Climate and Water Cycle Group

Prof. Christoph Schär

Observational data sets are employed to unravel the nature of the relevant interactions, and to detect variations and changes of the climate system.

Land-Climate Dynamics Group

Prof. Sonia Seneviratne

The group focus on the analysis of processes at the land-atmosphere interface, based on existing data (ground observations, satellite observations, observation-based datasets, model data) - in particular processes controlling soil moisture and land processes in general (droughts, vegetation, snow cover, ecosystem exchanges, land water and energy cycles) as well as land-atmosphere interactions and feedbacks.

Atmospheric Dynamics Group

Prof. Heini Wernli

Operational and reanalysis data from the European Centre for Medium-Range Weather Forecasts (ECMWF) are extensively used to analyse weather events and compile feature climatologies, like extratropical cyclones. Additionally, high-resolution numerical weather prediction data is provided by the Consortium for Small-scale Modeling (COSMO) to refine the weather analysis, for example over complex topography.

Atmospheric Predictability Group

Prof. Daniela Domeisen

The group makes extensive use of reanalysis data from a range of centers, including the European Centre for Medium-Range Weather Forecasts (ECMWF), the US National Centers for Environmental Prediction (NCEP), NASA, and the Japan Meteorological Agency (JMA), especially for high-altitude atmospheric variables in order to assess the dynamics and the impact on the surface. In addition, output from weather and climate prediction models is used, e.g. for forecasts on sub-seasonal (e.g. S2S database), seasonal (e.g. CHFP database) and climate time scales (e.g. CMIP5 database), in particular the MPI-ESM and ECMWF models.
