Martin Graus
Institution
Institute for Atmospheric and Cryospheric Sciences, University of Innsbruck
The Atmospheric Physics and Chemistry (APC) group at the Institute for Atmospheric and Cryospheric Sciences of the University of Innsbruck studies the chemical composition of the atmosphere using innovative approaches. New experimental concepts are explored that allow studying the exchange of trace constituents and their atmospheric transport and chemistry in the atmosphere, as well as testing and improving modeling concepts.
Short CV
Martin Graus has a Ph.D. in physics. He has extensive experience in online trace gas analysis with focus on the emissions and atmospheric fate of VOCs from biogenic and anthropogenic sources. To this end he conducted numerous experiments in the lab and in the field on various platforms (towers, aircraft, ships). He applies his expertise in instrument development and experimental design to push the boundaries of quantitative measurement and identification of organic trace gases in the atmosphere.

Institution
Institute for Atmospheric and Cryospheric Sciences, University of Innsbruck
The Department of Atmospheric and Cryospheric Sciences (ACINN) is one of the few university departments worldwide where research and education in atmospheric science and glaciology are co-located. Accordingly, ACINN's research focus lies on aspects of mountain meteorology, earth-atmosphere interaction - with a focus on snow- or ice-covered surfaces, exchange of gases and aerosols at the surface, exchange over complex topography - and ice-climate relations.
