In this section, it is intented to present the work performed by the TESLAS participants on the definition of the methodology of the lidar measurements to fulfill the general objectives outlined in the introduction. Previous studies using lidar systems to monitor ozone in the atmosphere have shown that the Dlfferential Absorption Lidar (DIAL) technique is the most efficient way to derive an ozone profile with good range and sensitivity [1--3]. Fluorescence or Raman-scattering measurements of pollutants are restricted to source monitoring where range and sensitivity requirements are not critical. In this subproject, the DIAL technique is then considered as the basic method for monitoring the vertical distribution of tropospheric ozone, but two spectral domains (UV and IR) were investigated, and various schemes are proposed for atmospheric interference corrections. The selection of the appropriate spectral domain and of the optimum correction algorithms are defined from numerical simulation studies using an atmospheric model and realistic lidar parameters. Before reporting the main findings of these calculations, the spatial and temporal scales and the concentration levels are described for tropospheric ozone monitoring.
