An Improved MODIS BRDF Radiometric Calibration Approach

Bi-directional reflectance characteristic is one of the most important factors of radiance distortion. This paper discusses the radiance distortion caused by ground bi-directional reflectance character and puts forward an improved bi-directional reflectance distribution function (BRDF) model based on kernel-driven model. The experiment of MODIS radiometric calibration shows that the improved approach is effective for MODIS radiance distortion.
