Evapotranspiration Data Access and Tools

NASA has evapotranspiration datasets that help researchers characterize how water is evaporating from land and vegetation. Access a range of data and data tools such as OpenET, AppEEARS, and Soil Moisture Visualizer to make the most of evapotranspiration data.

Featured Evapotranspiration Observation Method: ECOSTRESS
The ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station (ECOSTRESS) instrument measures the temperature of plants across Earth to assess the loss of water through the tiny stomata pores in their leaves. This loss of water through leaves is a key component evapotranspiration. Plants regulate their temperature by releasing water through stomata. Insufficient water availability will cause the temperatures of plants to rise, which can be measured with ECOSTRESS. The instrument can scan the entire Earth in seven days and with enough detail to determine the temperature of an individual farmer's field. The data is used to create the Evaporative Stress Index (ESI), a leading drought indicator and valuable resource for decision-makers.
