Solar spectral radiance simulation and sensitivity analysis in visible band

Abstract

Based on the current development of atmospheric satellite remote sensing technology and atmospheric radiation model, the latest version of SCIATRAN3.8 model is selected to simulate the solar spectrum radiance in visible band. After analyzing the structure and parameter classification assignment of the model. Combined with the theory of atmospheric radiation transfer, select the solar zenith angle, surface reflectance as parameters, simulate the solar spectrum radiance value in visible band, and sensitivity analysis is performed. On this basis, according to the research goal, compare the simulation of SCIATRAN3.8 and MODTRAN4.0. Which verifies the correctness of the SCIATRAN3.8 forward model, and provides a certain for the future research on atmospheric radiation transfer.
