Paper Abstract

Topographic effects and atmospheric effects are two main obstacles to further application of satellite imagery. In this paper, a new method has been developed in order to extract the surface reflectance over mountainous terrain. Three diffuse subcomponents are used to approximate the solar diffuse irradiance: circumsolar, horizon brightening, and isotropic diffuse flux. Topographic adjacency irradiance is calculated using a fit model. A digital elevation model is used to obtain information about surface elevation, slope, and orientation. And the atmospheric parameters such as water vapor content, aerosol optical depth are retrieved from MODIS data. Taking the rugged area in the southern section of Gao-Li-Gong Mountain for test, the result shows that the method has robust topographic and atmospheric correction ability.
