| 2. | Some variables regional distribution over south ningxia is given out in the course of evapotranspiration estimation : the regional distribution of surface characteristic parameters ( normalzed difference vegetation index , surface albedo , surface temperature ) , radiation balance components ( surface absorbed shortwave radiation , surface longwave radiation , atmospheric counter radiation , net radiation ) , surface heat and balance components ( soil heat flux , sensible heat flux , latent heat flux )
估算区域蒸发(散)量的过程中，得到许多有意义的量：地表特征参数(植被指数ndvi 、地表反射率、地表温度) ；地表辐射平衡各量(地表短波吸收辐射、地表长波辐射、大气逆辐射、地表净辐射) ；地表热量平衡各量(土壤热通量、显热通量、潜热通量) 。 |
