Abstract

Scenario analysis of a summer smog episode in Berlin P. Mieth, S. Unger, A. Sydow GMD - Research Institute for Computer Architecture and Software Technology, Rudower Chaussee 5, 12489 Berlin, Germany ABSTRACT A mesoscale model (Eulerian type) including a meteorological and dispersion part was coupled with the chemical scheme of Carbon Bond IV to investigate the ozone production in the conurban area of Berlin. In cooperation with the Environmental Agency of the Senate of Berlin a realistic summer smog episode was simulated. In order to find strategies for an effective smog management scenario analyses were computed under different emission conditions. A dominant influence of ozone con- centration and concentrations of precursor substances of ozone transported into the city on surface-near ozone concentrations is clearly visible. In case of typical meteoro- logical conditions for the region of Berlin a traffic reduction leads to an increase of the ozone concentratio
