Abstract
The backscattering linear depolarization ratios of major types of tropospheric aerosol particles (Asian and Saharan mineral dust, sea salt, and ammonium sulfate) were measured using a laboratory chamber for interpreting the polarization lidar measurement of tropospheric aerosols. The values obtained from Asian and Saharan mineral particles were to 0.05 ( deviation) for a high number of concentrations in the supermicrometer range and to in the submicrometer range. The values were for sea-salt crystals, for ammonium sulfate crystals, and for both liquid droplets in the submicrometer range. These values can serve as a reference for estimating aerosol type using lidar measurement.
