  1. COPS-TRACKS Air Pollution and Convection - The Lagrangian Experiment of the TRACKS Campaign W. Wilms-Grabe, U. Corsmeier, W. Junkermann, F. Holland, B. Neininger and Ch. Kottmeier

  2. TRACKS Transport and Chemical Conversion in Convective Systems (Coordination: Ch. Kottmeier) • 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 7th COPS Workshop Collège Doctoral Européen Strasbourg, France, 27 - 29 October 2008 TRACKS: Air Pollution and Convection W.

  20. Conclusions • 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. 7th COPS Workshop Collège Doctoral Européen Strasbourg, France, 27 - 29 October 2008 TRACKS: Air Pollution and Convection W.

  21. What do we learn? • 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. 7th COPS Workshop Collège Doctoral Européen Strasbourg, France, 27 - 29 October 2008 TRACKS: Air Pollution and Convection W.
