Main scientific contribution: My area of expertise is urban meteorology using a wide range of theoretical and experimental state-of-the-art methods. I have worked with surface exchange of atmospheric pollutants, greenhouse gases, energy and water above urban areas using the eddy covariance technique. Using the observations I have shown how the different surface exchanges depend on urban land cover, and how the processes should be parameterised in urban hydrological and surface urban energy balance models. I am one of the main developers of the Surface Urban Energy and Water balance Scheme (SUEWS) and my group uses the model to examine the impact of urban planning on the surface exchanges including urban carbon cycle and biogenic components. In my group we develop and utilise large eddy simulation model PALM to examine the impact of urban meteorology and urban planning to local air quality.
