Local scale air quality modelling

The group is involved in local scale air quality modelling of atmospheric compounds, for instance in development and validation of air quality models for different pollutants, especially particulate matter and nitrogen oxides. Local air quality models consider local emissions, e.g. from vehicular or stationary sources, regional emissions either using observed background concentrations or output of the regional air quality model, and the range of meteorological parameters.
