TS5.1 - Remote Sensing Determination of Evapotranspiration: Outcomes from the FAO Webinar Series (FAO, ICARDA, Sida)
Convener (s): FAOCo-convener (s): ICARDA, SIDA
Quantifying evapotranspiration (ET) in space and time is extremely relevant for water resources management, particularly in regions of scarce water resources like the Near East and North Africa (NENA). Several methods for ET determination have been developed at field scales that are, however, complex, expensive and prohibitive in costs when attempting to scale them up. Therefore, for large scales the only feasible and affordable methods for ET determination are through satellite Remote Sensing (RS).The session goals include: (i) updating the knowledge regarding RS ET determination, from the most common and adopted models to the latest advances; (ii) providing more clarity on the assessment of RS ET uncertainty and related acceptable limits for their field of application; and (iii) building awareness on the strengths, limitations, and fits-for-purpose for the range of RS ET models and databases available.
