卫星遥感数据的像元地面反射率反演计算

This paper presents a method of computation of ground albedo for satellite image pixel with a few scarely distributed ground data based on radiance correction of remotely sensed data. Firstly, a number of known ground data, including atmospheric transmittance, path radiance component of the value of remote sensed data and ground horizontal radiance for each pixel are used. Then, terrain effect on remote sensing value of each pixel is corrected with DTM. Last, inverse computation of ground albedo is conducted with the corrected data.
