Abstract

The regional air pollution model system EURAD has been applied to a SANA special observation period in August/September 1991. The trans- port pathways and distances of polluted air masses are analysed using tra- jectories calculated from the predicted fields of the meteorological mesoscale model MM5 - a part of the EURAD system. Furthermore the regional budget of ozone for East Germany is calcu- lated using mesoscale chemistry transport simulations. The dynamical and chemical processes which are responsible for the generation and removal of increased photooxidant concentrations are discussed. 1 Introdu
