Abstract

The paper presents the calculations of the light scattering matrix for quasi-horizontally oriented crystal ice particles. It is shown that in the general case the light scattering matrix for the transport equation is the function of seven variables, and for its calculation it is necessary to have a complete scattering matrix, depending on 9 independent variables. The report provides a number of simplifications that allow us to use of a light scattering matrix, depending on five variables, in radiation transfer problems, and that need the matrix as a function of four variables to calculate it. This approach significantly (millions of times) speeds up the calculations.
