Thermal model for discrete vegetation and its solution on pixel scale using computer graphics

In this paper, we discuss how the multi-reflection of thermal emission affe cts the calculation of radiation balance. With the help of computer graphic s, the four components of discrete vegetation are analyzed in detail and th e curves of BRDF for the discrete vegetation can be obtained as well. A new model is put forward to inverse the temperatures of four components. The s olution obtained by using computer graphics is consistent with observations in the field experiment in Yucheng Remote Sensing Comprehensive Site of GA S. Furthermore, the method can be used to retrieve land surface temperature based on multi-angle thermal infrared remotely sensed data.
