Aerosol-type-dependent lidar ratios observed with Raman lidar
[1] We summarize our Raman lidar observations which were carried out in Europe, Asia, and Africa during the past 10 years, with focus on particle extinction-to-backscatter ratios ( lidar ratios) and (A) over circle ngstrom exponents. For the first time, we present statistics on lidar ratios for almo...
