Abstract

In this work the result of calculation of backscattering matrices for non-spherical ice particles for 1.55 μm and 2 μm wavelengths is presented. The Physical Optics approximation method was used for solving this problem. The maximal dimension of particles varies from 10 μm to 1000 μm according to D. Mitchel dependency. The calculations were performed for random spatial orientation of particles. The results can be used for retrieving of microphysical properties (i.e. size and habit) of cirrus particles.
