Welcome to ECOSTRESS
On August 30th, 2019, the ECOSTRESS team received official guidance that the ECOSTRESS mission would be extended for a second year. A special thank you to the Early Adopters / Community of Practice for helping us and NASA understand all the ways ECOSTRESS data can be applied and for all of your feedback throughout this mission thus far.
On October 7th, 2019, NASA announced the selection of the science team for ECOSTRESS. The selections and abstracts are located <here>.

ECOSTRESS Overview
ECOSTRESS is addressing three overarching science questions:
- How is the terrestrial biosphere responding to changes in water availability?
- How do changes in diurnal vegetation water stress impact the global carbon cycle?
- Can agricultural vulnerability be reduced through advanced monitoring of agricultural water consumptive use and improved drought estimation?
The ECOSTRESS mission is answering these questions by accurately measuring the temperature of plants. Plants regulate their temperature by releasing water through tiny pores on their leaves called stomata. If they have sufficient water they can maintain their temperature, but if there is insufficient water, their temperatures rise and this temperature rise can be measured with ECOSTRESS. The images acquired by ECOSTRESS are the most detailed temperature images of the surface ever acquired from space and can be used to measure the temperature of an individual farmers field.
One of the core products that will be produced by ECOSTRESS team is the Evaporative Stress Index (ESI). ESI is a leading drought indicator - it can indicate that plants are stressed and that a drought is likely to occur providing the option for decision makers to take action.
