Abstract
Evapotranspiration (ET) is a key component of the water and energy cycles. In-depth knowledge about ET is of essence for a plethora of applications that include estimation of crop water consumption, irrigation scheduling and water resources management, modeling of hydrologic processes, forecasting of drought conditions, and monitoring of ecosystem response to climate change. Various proximal sensing methods may be applied in conjunction with the land surface energy balance or the terrestrial water balance to estimate ET at the local scale. In this chapter, we review state-of-the-art proximal ET sensing techniques along with their underlying theories.
