Abstract

A new concept to derive particle information from depolarization ratios obtained by a simultaneous three-wavelength depolarization lidar was presented. This new data treatment utilized the wavelength dependence of the ratio of the polarization components in the scattering light based on T-matrix computation. The results showed that calculated three-wavelength depolarization ratios can be used to characterize particle sizes of ice particles. Assessing the mixing of spherical and nonspherical aerosols, the presented method successfully reproduced the lidar data in real.
