Actual evapotranspiration in 2006 [PDF]

open access: yes, 2017
This layer represents the actual evapotranspiration in 2006, in million cubic meters. Volumes evapostranspirated are volumes of water that enters the atmosphere through evaporation from land and water surfaces as well as transpiration from plants.Data for other years are also available in the table.

Synthesis of Global Actual Evapotranspiration from 1982 to 2019 [PDF]

open access: yesEarth System Science Data, 2020
Abstract. As a linkage among water, energy, and carbon cycles, global actual evapotranspiration (ET) plays an essential role in agriculture, water resource management, and climate change. Although it is difficult to estimate ET over a large scale and for a long time, there are several global ET datasets available with varied algorithms, parameters, and

Closing the Feedback of Evapotranspiration on the Atmospheric Evaporation Demand Based on a Complementary Relationship

open access: yesAtmosphere, 2022
Evapotranspiration is the important feedback of the catchment into the atmosphere. However, in catchment hydrological modeling, the feedback of evaporation into the atmosphere is not closed and potential evaporation is always a meteorological forcing ...
