Light scattering matrix for bullet-rosette aggregates of atmospheric ice particles within the geometrical optics approximation

Abstract

The paper presents the elements of the light scattering matrix for atmospheric ice aggregated particles, consisting of "bullets" with the number of particles from 1 to 6. The calculation of the scattering matrices was carried out within the geometric optics approximation and single scattering. The spatial orientation of aggregates is random, the refractive index is 1.3116 (for a wavelength of 0.532 µm). The dependence of the light scattering matrix elements on the number of particles in aggregates is presented. The results can be used for interpretation of the data retrieved from laser sensing of crystalline clouds from ground and space.
