Gasphase and Aerosol Chemistry Group

MAIN GOAL

UNDERSTANDING THE PHYSICOCHEMICAL PROCESSES IN THE POLLUTED BOUNDARY LAYER AND ALPINE REGION

Energy use leads to emissions of nitrogen oxides and volatile organic compounds. The gas phase and aerosol chemistry group studies the processes including photochemical transformation, e.g. production of ozone, and meteorological transport from the tail pipe to high altitudes in the Alps. The research group at PSI is one of few leading groups in the world using the combination of state-of-the-art in-situ and remote sensing measurements of chemical species and meteorological parameters with photochemical transport models. The group has acquired a lot of experience in designing and performing field measurement campaigns. A main focus is to study the interaction of photochemical and meteorological processes over very complex terrain like the Alpine region.
