Optical and physical characterization of European and Indo-Asian pollution plumes with six-wavelength aerosol lidar

Abstract

Optical and physical particle properties of two typical pollution plumes emitted from the European continent during the Aerosol Characterization Experiment ACE 2, and from the Indo-Asian continent during INDOEX are characterized from six-wavelength lidar observations. In both cases effective radii were 0.1-0.25 mum. Complex refractive indices were 1.6-0.01i were obtained for the INDOEX case. Accordingly the single scattering albedo was 0.95-1.0 at 532 nm in the first case, but 0.8-93 in the second case.
