Abstract

The way for taking absorption impact into account for light scattering on atmospheric ice particles within physical optics approximation is presented. For arbitrarily shaped particle the calculations with three different conditions within physical optics approximation were conducted: without absorption accounting; simple absorption accounting before diffraction; absorption accounting based on diffraction on beam shape. The results show that with absorption accounting with using of all vertices of beam shape the different face function near backscattering direction.
