我们提出了一个简单的计划，估计在大的非均匀地区的地面蒸发遥感观测。我们的方法是基于容易测量的表面参数（如辐射表面温度）和有效的表面电阻的替代品之间的关系。初步结果，使用遥感数据集从AVHRR NOAA-14在南部大平原，显示出良好的一致性。所提出的方法似乎是更可靠的，易于适用于业务估计的蒸发大面积。
We propose a simple scheme to estimate surface evaporation over large heterogeneous areas using remote sensing observations. Our approach is based on a relationship between easily measured surface parameters (e.g. radiometric surface temperature) and a surrogate for effective surface resistance. Preliminary results, using remotely sensed data sets from AVHRR NOAA‐14 over the Southern Great Plains, show good agreement. The proposed approach appears to be more reliable and easily applicable for operational estimation of evaporation over large areas.
