Abstract :
Surface albedo is the ratio of the light-flux reflected in all directions of the ground and the total flux incident. It is a very important surface parameters. In this paper, atmospheric correction algorithm based on dark pixel method was introduced, and corrected surface reflectance in study area was obtained after pre-processing of the CCD data of HJ-1 Satellite. The surface albedo of study area was combined by the inversion formula which created by Liang Shunlin to converts albedo from narrowband to broadband, and then a correlation analysis of the results and accuracy given. The result presents that: the retrieval accuracy is reliable basically.
