Abstract

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.
