Paper Abstract

Asian-dust and Cirrus cloud have been measured by Multi-Wavelength aerosol lidar since 2000 and Automatic Controlled Aerosol lidar since 2002 at Suwon (127°E 37°N),Korea. These Lidars are Mie scattering scheme that use 355/532/1064 nm and 532 nm respectively. The vertical profiles of range corrected backscatter intensity and depolarization ratio on 16 days of Asian dust in springtime of 2002 are analyzed for this report. In Suwon, the Asiandust mainly showed at lower troposphere below 3 km but several cases showed in free troposphere of over 4 km. The peak depolarization ratios are in the range of 20-40%. The thickness of dust layer is about 2-2.5 km in case of lower tropospheric measurements. After event ofAsian dust the cirrus clouds are often measured in resemblance to Asian dust at upper troposphere. The maximum upper altitudes are about 8 to 12 km. The clouds falling down to about 3 km were measured which is a higher depolarization ratio of 10-30 %.
