森林潜热通量密度的遥感作图方法

   1)短波净辐射通量密度 定义为:

 

 

 

式中,是入射短波辐射  ; 是给定表面的

漫反射率。

2)长波净辐射通量密度通过下士确定:

 

 

式中,是在砂砾层表面测量的全波净辐射 

是砂砾层表面上的短波净辐射通量密度; 是砂砾层的发射率; 

Stephan-Boltzmann常数; 是砂砾层的温度; 是给定表面的

发射率;T是给定表面的温度。

3)某个像素在LOWTRAN-6波段6的原始数据对大气辐射及透射

的校正公式为:

 

 

式中,R是未校正的波段6原始数据; 是大气辐射; 是大气

透射系数。

4)真是表面辐射温度为:

 

 

式中,  

是半功率波数的倒数 是校正辐射。

 5)表面动力学温度 为:

 

 

式中,是表面辐射温度; 是表面发射率。
