Abstract
Solution to the problem of light scattering by hexagonal atmospheric plates and columns and irregularly shaped particles 10 to 100 mm in size is presented in the form of a databank of Mueller matrices. It is intended for interpretation of data from ground-based and space-borne lidars. The solution is obtained for typical wavelengths used in laser sensing: 0.355; 0.532; 1.064 mm, as well as for the wavelengths of the near-IR region: 1.55; 2 and 2.15 mm. The solution was derived with the use of the physical optics method. Based on the Mueller matrices calculated, the color and linear depolarization ratios were derived.
