Google Earth Engine ——非洲參考蒸發(fā)量（RET）數(shù)據(jù)集FAO/WAPOR/2/L1_RET_D

Reference evapotranspiration (RET) is defined as the evapotranspiration from a hypothetical reference crop and it simulates the behaviour of a well-watered grass surface. The value of each pixel represents the average of the daily reference evapotranspiration for that specific dekad.

參考蒸發(fā)量（RET）被定義為一個假設(shè)的參考作物的蒸發(fā)量，它模擬了一個澆灌良好的草地表面的行為。每個像素的值代表該特定德卡德的每日參考蒸發(fā)量的平均值。
