Introduction to ETa

This module offers an overview of actual evapotranspiration (ETa), exploring its calculation, modeling approach, products, characteristics, and considerations.

After completing this module, you will be able to:

• Describe how ETa is calculated
• Describe the characteristics of actual evapotranspiration (ETa) and the primary ETa products
• Explain the Simplified Surface Energy Balance operational modeling approach for ETa
• Evaluate the strengths, limitations, and important considerations when using ETa
