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.
NASA's ECOSTRESS Mission studies how plants use water by measuring their temperature from space. Join us to learn more about ECOSTRESS mission measurements, data and tools!
The ECOSTRESS, GEDI, and OCO-3 Earth observing missions aboard the International Space Station (ISS) will help scientists better understand Earth systems.
