Evapotranspiration (ET), the phenomenon of the loss of water into the atmosphere from the land surface through evaporation and transpiration, is an important part of water and energy cycles. ET is a key variable used in applications such as drought monitoring, climate prediction, water resources management, and agricultural planning. The importance of a high-resolution ET estimation has also been well identified for agricultural applications where site-specific monitoring is needed, which is highly relevant for a country like Nepal that relies on agriculture for the majority share of its GDP and employment workforces.
