Light scattering by hexagonal ice crystals of cirrus clouds with preferred orientations

摘要

The scattering (Mueller) matrices for hexagonal ice plates of various aspect ratios are calculated by the facet tracing method developed earlier. For horizontally oriented plates, the Mueller matrices depending on the incident angle have been obtained. The peculiarities inherent to the scattered light along the parhelic circle have been studied. A generalization of the data for small flatter of these plates relative to the horizontal plane is discussed.
