In order to know Asian dust particle distribution in the free troposphere, lidar measurements on scattering ratio (atmospheric aerosol density), depolarization ratio (nonsphericity of aerosol particles), and relative humidity were made in spring of 1994 at Nagoya using the Raman scattering effects. From discriminant analysis on those lidar data, six different type aerosols were identified; cloud particles, background free tropospheric aerosols, and four different groups of Asian dust particles (Kosa particles). The discriminant analysis of lidar return signal from atmospheric aerosols is useful way to identify Asian dust layers and to see mixing state of particle layers in the free troposphere.
