Module 1 webinars
This module is composed of one ‘setting-the-scene’ webinar plus eight key-note webinars that introduce the most widely used RS ET models (SEBAL, METRIC, ALEXI/Dis-ALEXI, SSEBop, ETLook, ETMonitor, SIMS and ETWatch). Each model key-note presentation will be then followed by a presentation reporting on the experience of its application, mostly within countries of the NENA Region.

Session 9: SIMS (Satellite Irrigation Management Support)
Date: 26 May 2021
Time: 5 PM (GMT +2)
This webinar will provide a brief description of key algorithms, step-wise synoptic view of calculation procedures to arrive to ET, where input data are coming from, which sensors are used, what spatial, temporal and spectral resolutions are used, what are the critical steps prone to errors, what to do to reduce errors, strengths and weakness of the model, expected uncertainty, best application purposes and brief examples.
