Abstract

The purpose of this report is to describe the lidar measurement of depolarization ratios of particulate matter (Depolarization Ratio of Yellow Sand) and to discuss the transformation of aerosols due to Yellow Sand event. The scattering profile shows high level during Yellow Sand event and scattering layers are thicker as compared to other seasons in about 3 .sim. 8km, and the values and mode height of scattering ratio corresponed with depolarization ratio. A distribution of total depolarization ratio during the observation period was 44.7 percent among total cases of 0.03 < Dt < 0.5 with scattering ratio > 30 and relative humidity < 30 was satisfied (popular Yellow Sand type).
