heal.abstract	Coordinated measurements during a number of Saharan dust transport events were performed at several stations of the European Aerosol Research Lidar NETwork (EARLINET). During the period 2001-2002, 12 cases were captured at Thessaloniki, Greece (40.5°N, 22.9°E) with a 355nm Raman lidar system. Backward trajectories and model calculations from the DREAM model confirmed the existence of Sahara dust in all cases examined. Within the dust plumes that were indicated by the model, the lidar ratios ranged from 25 to 80 sr and the backscatter related Angstrom exponent (color index) ranged from -1 to 3. A significant anticorrelation was found between the lidar ratio and the color index during the Saharan dust events occurring over Thessaloniki. Model calculations partly explain this anticorrelation, while in certain cases mixing with boundary layer aerosols makes the separation of dust in the lidar measurements difficult.	en
