Abstract

Study on radiation transfer, which is the key process in the energy balance system, is required to interpret remote sensing data and support application. In the radiation transfer process, atmospheric transmittance is the most important physical parameter in study of remote sensing, especially in the quantitative remote sensing. The paper mainly studies on atmospheric transmittance based on MODIS and FY. In the paper, it calculates gaseous absorption of seven gases including water vapor, carbon dioxide, ozone, nitrous oxide, carbon monoxide, methane, and oxygen (H₂O, CO₂, O₃, N₂O, CO, CH₄ and O₂) by MODTRAN. Then it makes convolution transforms, fit and regress the polynomials to obtain the corresponding coefficients of each polynomial and different relative spectral response. At last, it calculates atmospheric transmittance by the fitted polynomials compared with the results of MODTRAN to validate. Based on the study, it lays a foundation for studying and application on Daily BRDF/Albedo Algorithm for FY-3 next.
