NOAA/AVHRR资料的订正模型

 

(1)    绿度总值的校正――各层平均绿度值模型:

 

 

式中,为各层总绿度值;为各层像元数(不包括空白点);为树木、杂草、蔬菜的绿度值,为层的序号1,2,3n为树草菜序号1,2,3/万亩,分别为树木、草场和菜园占有的绿度值。

 

(2)    AVHRR资料的大气影响校正――反射率R模型:

 

 

式中,为地面目标的反射率;为地物和卫星间的大气透过率;为大气路径辐射。

 

(3)    区域订正值B模型:

 

 

式中,分别为植被指数的实际值和理论值。

 

(4)    积温校正――绿度积温订正值模型:

 

 

式中,值为建立方程时积温值与预报时积温值之差;表示每增减1℃积温时,绿度值的增减值。
