| Abstract | We observed the intense elevated Asian dust events on April 30, 2005 with a multi-wavelength Mie-Raman lidar based on Nd:YAG lasers in Tokyo, Japan. The highly depolarizing layer indicating dust signature exhibits a large discrepancy in the lidar ratios between 355 and 532 nm, i.e., the lidar ratios at 355 and 532 nm were 58.4 ± 6.1 and 41.7 ± 4.6 sr. We have compared the observations with the calculations using T-matrix theory [1] taking account of the non-sphericity of the mineral dust. The wavelength dependence is explained partly without introducing the wavelength dependence of the refractive index of the dust particle. |
