Abstract

The observed radiance at-sensor level generally records the radiation changes caused by multiple factors during the imaging process for Earth observation satellites. Most methods can not retrieve the precise reflectance because of the neglecting of the mutual effects between the atmosphere and the topography. In this study, based on a physical component model of at-surface level radiation, demonstrates that the earth-atmosphere coupling effect is playing a key role in a practical reflectance retrieval method over rugged terrains. The comparison of retrieving reflectance on sunlit areas and shady areas shows how the accuracy is affected after applying earth-atmosphere coupling correction.
