Paper Abstract

The paper presets the research results of the influence of hexagonal ice column’s dihedral angle of 90° distortions on the backscattering matrix. The solution of the light scattering problem for hexagonal ice columns is obtained within the physical optics approximation. The results are obtained for hexagonal ice columns with lengths of 10, 31, 100, 316, 562, 1000 microns and diameters of 7, 22, 70, 123, 165, 220 microns, respectively. The distortion angle of the dihedral angle of 90° runs within the range of 0° (regular particle) to 10°. The calculations were carried out for the wavelength of 532 nm. The refractive index was assumed to be 1.3116. In addition to the backscattering matrix, the geometric scattering cross section and the important optical characteristics such as the lidar and depolarization ratios were calculated. The results showed that the influence of deformation on the optical characteristics increases with the particle size.
