| Abstract: | Studies of the dispersion of pollutants (SO2, O3) in the planetary boundary layer have been performed during the Fos Berre 1983 International Campaign using ground-based DIAL lidar operating in the u.v. wavelength range. Multidimensional measurements of both SO2 and O3 were obtained with a spatial resolution better than 500 m, a temporal resolution of 3 mn and a maximum horizontal range of 3 km. The overall accuracy as assessed by various comparisons with other measurement systems was always better than 20%. Examples of application to studies of SO2 dispersion in the planetary boundary layer, of plume evolution and of horizontal inhomogeneities in the ozone field are given. |
