QUANTITATIVE APPROACH TO SCATTERING AND THERMAL EMISSION OF SNOW ICE
冰雪散射和热辐射的定量研究

By using an image of snow sample, the correlation function and correlation length were obtained experimentally. Then the effective radius of discrete spherical scat-terer in the radiative transfer model was determined. By solving the vector radiative transfer equation for a slab of densely-distributed scatterers, the polarized brightness temperatures, including multiple scattering effect, from a layer of snow were numerically calculated, and favorably compared with the measurements from spaceborne remote sensing.
