Paper Abstract

Asian dust have been measured by Multiwavelength lidar which supplied with three wavelengths (355, 532 and 1064 nm) laser and multimode receiver system. The system provides three modes of receiving system of Aerosol (355, 532 and 1064 nm), Raman (387, 408 and 355 nm) and Polarization (532 am) measurements. Six cases of Asian dust profiles from 5 km upto 12 km are achieved in spring of 2000. As the results, we can see the backscattering ratio of aerosol and Asian dust shows similar value that is in the range of 1.2 to 3, but the values of depolarization ratio is large that over 15% of Asian dust than below 10% of aerosol. Also, the concentration of large particle size over O.7O7tm is increased when in cases of Asian dust.
