Data bank of light scattering matrices over the all scattering directions for atmospheric ice particles of cirrus clouds, calculated within the approximation of geometric and physical optics

Abstract

The paper presents the results of comparing numerical solutions to the problem of light scattering on atmospheric ice particles by methods of geometric and physical optics. The solution was constructed for hexagonal shaped particles (hexagonal ice column) and droxtals. The results of the comparison of the light scattering matrix over the entire sphere of the direction showed that in the direction of scattering strictly backward, the use of the geometric optics approximation can lead to significant errors, especially for hexagonal particles, which are characterized by the presence of angular reflection
