The spread of mineral particles over southwestern, western, and central Europe resulting from a strong Saharan dust outbreak in October 2001 was observed at 10 stations the European Aerosol Research Lidar Network (EARLINET). For first time, an optically dense desert plume characterized coherently with high vertical resolution on continental scale. main layer located above boundary (above 1‐km height sea level (asl)) up to 3–5‐km height, traces reached heights 7–8 km. particle optical depth...
