Abstract
Basic characteristics of optical scattering in a mixed-phase cloud (asymmetry parameter of the scattering phase function and efficiency scattering factors and scattering coefficients) are considered. Theoretical consideration is based on the mixed-phase cloud model in the form of a uniform mixture of ice crystals and water droplets. Expressions allowing calculation of asymmetry parameter of the mixed-phase cloud scattering phase function are obtained as functions of the cloud temperature, average size of cloud particles, and ratios of the number densities of differently shaped ice crystals. Data calculated for the asymmetry parameter of infrared scattering in a mixed-phase cloud layer at its given temperature are presented.
