2 TRACKS Transport and Chemical Conversion in Convective Systems (Coordination: Ch. Kottmeier) 2 7 th COPS Workshop Collège Doctoral Européen Strasbourg, France, 27 - 29 October 2008 TRACKS: Air Pollution and Convection W. Wilms-Grabe et al. Aims of TRACKS:  Vertical transport and chemistry of trace gases in convective systems and above complex terrain  Dilution of pollutants and cleaning of PBL  City plume in a convective boundary layer: transport and chemistry of trace gases

20 Conclusions 20 7 th COPS Workshop Collège Doctoral Européen Strasbourg, France, 27 - 29 October 2008 TRACKS: Air Pollution and Convection W. Wilms-Grabe et al.  City plume of Karlsruhe was detected under convective weather conditions.  NO2 didn‘t show a very high but nevertheless a clear signal of mass flux into the lee of Karlsruhe.  Ozone was build up about 4-6 ppb on a distance about 40 km from emission sources.  CO2 increases due to CO emissions and photochemistry by about 4 ppm.  PM10 aerosols show a „typical plume behaviour“.  O3 of Dimona too high.  The Karlsruher city plume of 25/07/07 is not an extreme event, but show ordinary conditions.

21 What do we learn? 21 7 th COPS Workshop Collège Doctoral Européen Strasbourg, France, 27 - 29 October 2008 TRACKS: Air Pollution and Convection W. Wilms-Grabe et al.  The use of a Zeppelin as measurement platform is helpful, but more experience with the Zeppelin is essential.  Transport processes of air pollutants during moderate convective conditions could be investigated. This knowledge is important for studies of vertical transport and studies due to the healthy of the population.  DO 128 provides reliable trace gas data also for further IOPs. What do we plan?  Modelling the Lagrangian experiment with COSMO-ART.  Investigation of vertical transport processes in convective systems.
