Abstract
The paper presents a solution to the problem of light scattering on atmospheric ice crystals of irregular shape. In this work, the calculation and study of backscatter ratios: the backscattering cross section, lidar and depolarization ratios of ice hexagonal particles, the right dihedral angle ξ of which was distorted in the range from 0° (regular particle) to 50°, were carried out. The calculation was performed for random oriented ice crystal particles of irregular shape: a double hexagonal bullet, hollow and distorted hexagonal columns. The calculations were carried out within the physical optics approximation, the wavelength of the incident light was taken equal to 1.064 μm, and the refractive index was 1.3004. The results of a comparison of the optical properties of the investigated particles are presented.
