Water Accounting Plus

MOOC WaPOR Concepts and Validation

This MOOC offered by IHE Delft and FAO was launched in June 2023!

IHE Delft Institute for Water Education and FAO have developed a new MOOC! This course aims to provide a better understanding of the theoretical concepts used to generate remote sensing based data on evapotranspiration and biomass production including their limitations. Specific attention will be given to the WaPOR database and how a systematic validation of the data can be done. The flyer can be downloaded here

Learning Objectives

Upon the successful completion of the course, the participants will be able to

  • Explain the principles of thermal remote sensing and surface energy balance concepts
  • Identify global ET data products and categorize the approaches used for producing them
  • Explain WaPOR methodology and ETLook model
  • Describe spatial and temporal attributes of WaPOR database inputs
  • Explain the quality assurance cycle and the role of data validation
  • Describe validation techniques and steps for WaPOR data products
  • Calculate performance metrics to validate WaPOR data products (PCP, RET, AETI, NPP, biomass)
  • Discuss the limitations and challenges of ET models and WaPOR database products

The course is organised into three modules:

  • Module 1: “Concepts of remote sensing ET (energy balance, FAO-56 PM)” 
  • Module 2: “WaPOR database: structure, input data, and methods” 
  • Module 3: “Validation of WaPOR database products”

Important dates:

  • 1 June 2023 registration open
  • 15 June 2023 course open

‚ÄčThe course is free to attend and is open to all who are interested. The course is self-paced and you can start any time. A reliable internet connection is required. A certificate of completion can be obtained after completing all assignments. 

Target Group: Early and mid-career water professionals with a technical background and a strong interest in new techniques for water use monitoring.

Pre-requisites: Preferably a relevant water and/or environmental science (agriculture, remote sensing, geoinformation, geography, or any other relevant) degree; basic working knowledge of spatial data and analysis techniques. Recommendation to have finished module 1 of the MOOC on Water Productivity and Water Accounting using WaPOR before starting this course. Good command of the English language is required.

For fundamentals of remote sensing, the following free online courses are recommended:

Land in Focus – Basics of Remote Sensing
ARSET - Fundamentals of Remote Sensing
