Method for Estimation of Multiple Reflection, Scattering and Absorption in Mountainous Areas of Remote Sensing Satellite Data

Abstract

Method for estimation of multiple reflection, scattering and absorption in mountainous areas of remote sensing satellite data is proposed. An experiment of TOA: Top of the Atmosphere radiance evaluation for miniature forest with slope grades, tree species, tree canopy shapes in modeled V-shape mountainous areas is conducted. Through experiments, it is found that the influences due to multiple reflection between two slope surfaces are quite significant; the maximum radiance rates are about 4% to 5%. It is also found that the multiple reflection can reveal important differences in clarifying radiative transfer process in atmosphere. The results are also simulated by means of Monte-Carlo based radiative transfer model with forestry surface model.
