Paper Abstract

Light scattering by ice crystals of cirrus clouds is described by the geometric optics approximation with a good accuracy. This approximation is realized numerically with various ray-tracing codes. However, a majority of authors apply the ray-tracing codes not to the electromagnetic field but to its quadratic quantities, for example, to the Stokes parameters. Though this approach simplifies essentially calculation algorithms, the wave effects like diffraction and interference turn to be ignored. In this paper, ray- tracing is applied directly to the electro-magnetic field yielding the Jones matrix of the scattered field. As a result, two scattering (Mueller) matrices appear called the pure and mixed Mueller matrices. Here, the pure Mueller matrix is obtained via the Jones matrix by means of a simple transformation and the mixed one is a sum of the field quadratic quantities. A problem appears: which of the matrices is measured at lidar sounding of cirrus clouds?
