A Parameterized Radiative Transfer Model for Spaceborne Remote Sensing Application
用于空间对地遥感的一个参数化辐射传输计算模式

It is of great importance to develop a simple but exact model for calculating outgoing radiance to the application of atmospheric correction in spaceborne remote sensing Based on relationship of the radiance to such parameters as atmospheric scattering phase function, optical depth, solar zenith angle, viewing azimuth and zenith angle, by using a lot of accurate radiance data, a parameterized model for calculating outgoing radiance is developed According to 39440 sets of comparative numerical simulations, in the condition of the optical depth less than unity, the solar zenith angle of <72 o _ and the viewing zenith angle of <65 o , errors in radiance calculated by the parameterized model are generally less than 6% The larger the surface reflectance, the higher the model accuracy The accuracy gets worse with increasing optical depth and solar zenith angle
