Abstract

Lidar depolarization measurements were performed simultaneously at two wavelengths (532 and 1064   nm ) in an Asian dust event. The observed particle depolarization ratio for 1064   nm was generally larger than that for 532   nm , and it was found that the mixing of Asian dust and other spherical aerosols must be taken into account. A simple two-component theory considering two types of aerosol (dust and spherical aerosols) was developed and applied to the observed data. The mixing ratio of dust and the backscatter-related Ångström exponents for dust and spherical aerosols was derived. These parameters can be used to infer characteristics of the aerosols and the mixed states.
