EO Africa Webinar #4: Evapotranspiration from Space

 March 25 @ 14:00 - 15:00 UTC+2

4th on the EO AFRICA R&D Facility Webinar Series

This webinar is devoted to evapotranspiration (ET) monitoring with Earth Observation (EO) satellites.

The webinar is going to have four parts:

  • During the first 20 minutes, the concept of ET and the Food and Agriculture Organization (FAO) Penman (1948) – Monteith (1965) approach to its modelling will be explained.
  • Then in 10 minutes the demonstration of a large scale FAO ET dataset WaPOR https://wapor.apps.fao.org/home/WAPOR_2/1 will take place.
  • In the last 30 minutes, a local scale Two-Source Energy Balance (TSEB, Norman, Kustas and Humes, 1995) model will be explained followed by its Sentinel Application Platform (SNAP) plugin realization (Sen-ET) demonstration. The sharpening of Sentinel-3 1 km Land Surface Temperature (LST) to Sentinel-2 20 m resolution is the key feature of the approach.
  • If time permits an ESA’s Third Party Missions Programme Landsat-based approach will be demonstrated.

Questions in between the sections and at the end of the webinar are most welcome.

The duration of the webinar is 1 hour. During the webinar, there is a live chat available.

Required: For participants who would like to reproduce the actions of the presenter, the registration on WaPOR FAO portal https://wapor.apps.fao.org/sign-in is needed.

Optional: For participants who would like to use the Sen-ET plugin (https://www.esa-sen4et.org/) in their research, a Windows-based ESA SNAP installation with configured Python 3.6 is needed. The setting-up issues might be tackled during the QA session. An alternative to SNAP is a Python-based version of TSEB, PyTSEB, which implies some knowledge of Python.

The webinar will be executed under the framework of the EO AFRICA R&D Facility by the University of Twente – Faculty of Geoinformation Science and Earth Observation.
