Abstract

The given work is devoted to theoretical investigation of optical radiation absorption by non-spherical shapes ice particles. For oriented crystals it is shown that the change of absorption coefficient in the greater degree is connected to volumes of crystals, and the spectral behavior in the infrared follows the features of the spectrum of absorption index of ice. Application of "vector-parametrical method" essentially simplifies consideration of the numerous tasks concerning changes of polarized characteristics of light beam passing through anisotropic environments. There is considered an absorption coefficient vector. Variations of physical parameters such as, sizes, shapes, refractive index, and orientation of crystals and also length of wave of incident radiation support the changes of elements of extinction matrix and phase matrix for oriented particles which determine the absorption coefficient vector. Thereupon IR range from optical spectrum of wavelength is more preferential to study the optical characteristic of ice clouds.
