NEAR-INFRARED LIGHT SCATTERING BY ICE-WATER MIXED CLOUDS

Abstract

Based on the Mie theory, the light scattering properties of clouds consisting of pure water, pure ice spheres and concentric waterice spheres are studied in the near-infrared regions, respectively. We computed the single scattering albedo, phase function, and asymmetry parameters of water clouds, ice clouds, and ice-water mixed clouds. The near infrared reflectivity of the ice-water mixed clouds is computed by using the adding-doubling method and compared to the other two types of clouds. It is shown that it is possible to use the near infrared reflectivity to derive the microphysical characteristics of the clouds.
