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

Submit an Abstract to this Session



Session ID#: 34375

Session Description:
The estimation of evapotranspiration (ET) is prone to large uncertainties. This session will cover both in situ and satellite-based estimations of ET. In situ methods (lysimeters, eddy covariance, Bowen ratio, sap flow, etc.) are important for understanding ET processes and the verification of remote sensing and modelling results, but are also prone to systematic and random errors, especially in biologically diverse and topographically complex systems. The sources of bias and uncertainty and their importance tend to vary by instrument type, environment, spatio-temporal scale, and modeling approach. Thus, ET maps from upscaled in situ and remotely-sensed data can vary considerably. The scope of the session will include (1) ET estimation with in situ devices: improved methods and upscaling approaches and analysis of long time series; (2) advances in ET estimation by “remote sensing” using optical and thermal bands; (3) applications for a range of spatio-temporal scales and (4) ET estimate inter-comparisons.
