%X Atmospheric upward and downward radiations in visible and near-infrared bands are the key input parameters for radiative transfer modeling, imaging simulation and atmospheric correction. This study presents the numeral models and computing methods of the atmospheric parameters which are related to the two parameters according to four-stream radiative transfer theory. Focusing on the six bands of Landsat 5 TM, the parametric models among atmospheric parameters, water vapor content, visibility distance and solar incidence zenith angle were designed, based on which the sensitivity of each parameter is analyzed. The results showed that the parametric models have higher precision. Meanwhile, the atmospheric upward and downward dif-fuse radiation of each band for TM remote sensing was calculated and the changes under the coverage of vegetation and bare soil were analyzed.
