H31J:
Evapotranspiration: Advances in In Situ Measurements and Remote Sensing Based Modeling Approaches I


Session ID#: 10578

Session Description:
Evapotranspiration (ET), linking energy and the water cycles, is one of the fluxes most challenging to quantify in hydrology. Because its determination is prone to large errors, marked differences exist between various methods. This session will cover both in situ and satellite-based estimations of ET. In situ methods (lysimeters, eddy covariance, Bowen ratio, 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. However, sources and magnitude of bias and uncertainty tend to vary by method/hydro-climate. The scope will include (1) estimation with in situ devices: improved methods and analysis of long time-series, (2) advances in “remote sensing” using energy and water balance principles (SEBAL/METRIC, Two-Source/ALEXI, SEBS, SSEBop, MOD16, GLEAM, CMRSET, P-M/P-T based, e.t.c.), and (3) applications for a range of scales: daily, yearly, and from field-scale agriculture to basin-wide water budget studies.
