Interpretive Summary: The purpose of this article was to demonstrate the need for use of common evapotranspiration (ET) vocabulary and understanding of standardized ET methods within the agroecosystem modeling community. We discuss the important difference between reference ET and potential ET, give examples of how these concepts have been misapplied in cropping systems models, give examples of communication barriers between ET practitioners and modelers, and give suggestions for priorities moving forward.
Technical Abstract: Although standardized evapotranspiration (ET) methods have been available for decades, they are commonly misunderstood, miscommunicated, and misused, especially within the agroecosystem modeling community. Some models misapply or misname standardized ET methods unbeknownst to users, and there is confusion in communication between ET practitioners and modelers. By highlighting some of these issues, we demonstrate and suggest the need for improved and consistent communication and application of standardized ET methodology.
