The Multiphase Chemistry group performs laboratory studies related to the chemistry, photochemistry and kinetics of atmospheric multiphase processes involving organic, halogen, nitrogen oxide and odd oxygen species on substrates relevant for aerosol particles, cirrus ice, ocean surface, soil surfaces, snow and sea ice. Understanding these processes is relevant for the assessment of the human impact on atmospheric composition, climate, human and ecosystem health.
We use a combination of in-situ spectroscopy, flow tube and chamber techniques to cover scales from molecular level world of interfaces to the microstructure in aerosol particles and to the mesosopic medium of snow.
We educate young scientists in laboratory atmospheric chemistry within the frame of the Institute of Atmospheric and Climate Sciences (IAC) at ETH Zürich (Department of Environmental Systems Sciences, D-USYS).
