Abstract

The article presents the data bank of light scattering matrices for ice hexagonal particles with a preferentially horizontal spatial orientation. The calculations were performed within the geometric optics approximation for flutter angles from 0 to 180 degrees in increments of 1 degree. It is shown that the light scattering matrix for randomly oriented ice crystals of cirrus clouds is fundamentally different from the light scattering matrix for particles with a preferentially horizontal spatial orientation. This fact can play a significant role in solving the radiation transfer problem through cirrus clouds and have to be taken into account in climate modeling.
