Google Earth Engine ——非洲土壤蒸发和截流（ETIa）数据集

The actual evapotranspiration and interception (ETIa) (dekadal, in mm/day) is the sum of the soil evaporation (E), canopy transpiration (T), and evaporation from rainfall intercepted by leaves (I). The value of each pixel represents the average daily ETIa in a given dekad.

实际蒸发和截流（ETIa）（dekadal，单位：毫米/天）是土壤蒸发（E）、冠层蒸腾（T）和叶片截获的降雨蒸发（I）之和。每个像素的值代表一个特定dekad的平均日ETIa。
