[περίληψη] Aerosol measurements have been performed in Greece since 1994, using a backscattering lidar system. The main scientific objective has been to evaluate the vertical structure of the Planetary Boundary Layer (PBL) in urban sites of Greece, using suspended aerosols as tracers of the atmospheric motion. The observations presented here were performed in early 1996, over the city of Thessaloniki in Northern Greece, close to the sea shore. The lidar system was operated under varing air pollution and meteorological conditions. The vertical profiles of the aerosol extinction and backscattering coefficients were retrieved from the lidar signal, using the Fernald-Klett inversion algorithm. Comparison between standard meteorological data from radiosondes and ground stations proves that lidar aerosol profiles can be successfully used to monitor the time variation in the layering of the lower troposphere.
