Personal profile


Atmospheric dispersion, aerosol dynamics modelling and human exposure estimation at regional, urban and street scale with strong focus on particles and gaseous air pollutants. Using e.g. microscale model MISKAM or street canyon model OSPM and the DEHM/UBM/AirGIS exposure modelling system.


Matthias Ketzel is Professor in the Section of Atmospheric Modelling at the Department of Environmental Science, Aarhus University and Visiting Professor at the Global Centre for Clean Air Research (GCARE), University of Surrey, U.K. He received his PhD from Lund University, Sweden. He has a background in physics and fluid dynamics and has more than 30 years of experience within the field of atmospheric science and in  human exposure assessment and local scale atmospheric dispersion modelling.
