Abstract

The paper presents the characteristics of light scattering on ice particles of cirrus clouds within the physical optics approximation for wavelengths of 0.355, 0.532, 1.064, 1.55 and 2 μm. The calculation was carried out for hexagonal ice columns and particle with arbitrary shape with their random spatial orientation. Particle sizes range from 10 to 1000 microns. It is shown that the color ratio of a polarization lidar operating at wavelengths of 0.532, 1.064, and 1.55 μm allows one to construct algorithms for retrieving the particle size in cirrus clouds.
