Each year an individual assignment of a specific topic (related to field work) will be made for interested students who will acquire knowledge in experimental, instrumental, or numerical aspects of atmospheric chemistry. Partly self-organized project requiring independent work in a small group.

This course covers the chemical and physical processes controlling the composition of the troposphere and stratosphere and introduces the relevant fundamentals for processes in the gas phase, in aerosols and clouds. These concepts are explored in the context of key environmental issues, such as urban air pollution, stratospheric ozone depletion, and air quality connections to climate change.

This atmospheric chemistry laboratory course introduces students to state-of-the-art instruments and methods for the investigation of the physico-chemical properties of aerosol particles at the Laboratory of Atmospheric Chemistry (Paul Scherrer Institute). We will use a flowtube to coat black carbon particles with organic material and to observe the changes in their physical-optical properties.

Measuring Techniques: Environmental Monitoring, Trace Gas Detection, Remote Sensing, Aerosol Characterization, Techniques used in the laboratory.

The field course offers the opportunity to carry out atmospheric physical and chemical experiments. Students can acquire knowledge in experimental, instrumental, numerical or theoretical aspects of atmospheric sciences.
