Evapotranspiration (ET) is a key landscape response variable that links the soil-water-vegetation system with the atmosphere through bio-physical processes for mass and energy exchange. The estimation of ET is prone to uncertainties. This session will cover both in situ and satellite-based estimations of ET over land and water. In situ methods (lysimeters, eddy covariance, Bowen Ratio, sap flow, scintillometer, etc.) are essential for understanding ET processes, field verification, and bias-correction of remote sensing and modelling approaches. Satellite-based estimations are important for large area ET mapping and basin scale applications. However, sources and magnitude of bias and uncertainty vary by method and hydro-climatic region. The scope of the session will include: (1) in situ techniques (methods and analysis), (2) ET modeling using optical and thermal sensors, (3) applications for a range of ecosystems and spatiotemporal scales, and (4) accuracy evaluation in relation to relevant decision making in water resources management.
