Evapotranspiration Partitioning in Selected Subtropical Fruit Tree Orchards Based on Sentinel 2 Data Using a Light Gradient-Boosting Machine (LightGBM) Learning Model in Malelane, South Africa

Hydrology
The accurate estimation of evapotranspiration (ET) and its components are vital for water resource management and irrigation planning. This study models tree transpiration (T) and ET for grapefruit, litchi, and mango orchards using light gradient ...
