COMBINED LIDAR REMOTE-SENSING OF OZONE IN THE PLANETARY BOUNDARY-LAYER AND SF6 TRACER DISPERSION EXPERIMENTS DURING SCHAUINSLAND-95

The chemistry and transport of ozone in the planetary boundary layer h ave been investigated within the frame of the field experiment ''Schau insland '95''. For the first time lidar and sodar remote sensing have been used in combination with tracer dispersion experiments. The main purpose of this work is to present time series of vertical profiles of ozone concentrations measured under well-chosen meteorological and to pographical conditions. The combination of the applied methods allows the interpretation of the ozone values in terms of standard atmospheri c stratification. The results on the distribution and vertical extent of the ozone concentration specify the photochemically active reaction volume in the atmosphere and constitute an important source of inform ation for the modeling of atmospheric chemistry. The impact of atmosph eric transport on ozone pollution in suburban and rural locations with complex topography is briefly discussed.
