Abstract

Development of a Microscale Gas-Phase Chemistry Mechanism for Implementation in the Microscale Model MITRAS A contribution to subproject SATURN Sebastian Trepte and Thomas Schoenemeyer Fraunhofer-Institute for Atmospheric Environmental Research, Kreuzeckbahnstr. 19, D-82467 Garmisch-Partenkirchen, Germany Problems and aim of the project For defining efficient air pollution abatement strategies it is essential to understand the fundamental mechanisms of transport and transformation of air pollutants at extremely high concentrations. Since a significant fraction of precursor substances for the formation of ozone and other photo-oxidants are emitted within European cities, the transport and transformation processes need to be studied in street canyons, in addition to the mesoscale processes. Pollutants emitted by traffic and other local sources contain substances which are very reactive and consequentl
