ECOSTRESS

The instrument that collects this data is a multispectral thermal infrared radiometer. It measures temperatures on the surface of the Earth, rather than surface air temperature.{{cite web |url=https://ecostress.jpl.nasa.gov/news/1aaaaabnasas-la-hot-spots-image|title=ECOSTRESS Maps LA's Hot Spots|website=ecostress.jpl.nasa.gov|publisher=Jet Propulsion Laboratory|date=September 18, 2018}} {{PD-notice}}{{cite press release|url=https://eurekalert.org/pub_releases/2018-06/uoq-ucd062818.php|title=UQ center's data used in space station study of global climate|publisher=University of Queensland|via=EurekAlert!|access-date=2018-10-02}} Dr. Simon Hook{{Cite web |title=JPL Science: Simon Hook |url=https://science.jpl.nasa.gov/people/Hook/ |access-date=2022-10-27 |website=science.jpl.nasa.gov}} is the principal investigator of the ECOSTRESS mission and Dr. Joshua Fisher{{Cite web |title=Joshua Fisher |url=https://science.jpl.nasa.gov/people/JFisher/ |url-status=dead |archive-url=https://web.archive.org/web/20161001234622/https://science.jpl.nasa.gov/people/JFisher/ |archive-date=1 October 2016 |website=JPL Science}} is the Science lead; both are located at NASA's Jet Propulsion Laboratory (JPL).

The data collected is also published via the open-access TERN Data Discovery Portal in Australia.

The ECOSTRESS radiometer was built at JPL and consisted of 5 spectral bands in the thermal infrared (8-12 micron) and 1 band in the shortwave infrared, which is used for geolocation.{{cite web |title=Instrument |url=https://ecostress.jpl.nasa.gov/instrument |website=ECOSTRESS}} ECOSTRESS was delivered to the ISS by the SpaceX Dragon after a launch out of Cape Canaveral, Florida on 29 June 2018{{cite web |url=https://www.jpl.nasa.gov/news/news.php?feature=7179|title=ECOSTRESS Launches to Space Station on SpaceX Mission|publisher=NASA/JPL|access-date=2019-08-13}} {{PD-notice}} The Dragon arrived at the space station on 3 July 2018. The radiometer was mounted on the station's Kibo module. The radiometer constituted about {{cvt|550|kg}} of the {{cvt|2700|kg}} of cargo on board the Dragon.{{cite press release|url=https://phys.org/news/2018-07-ecostress-space-station-spacex-mission.html|title=ECOSTRESS launches to space station on SpaceX mission|publisher=Jet Propulsion Laboratory|via=Phys.org|access-date=2018-10-02}} Other cargo included spare parts for the Canadarm2 robotic arm, as well as other equipment and supplies.

The key science questions that ECOSTRESS is addressing include:

1. How is the terrestrial biosphere responding to changes in water availability?
2. How do changes in diurnal vegetation water stress impact the global carbon cycle?
3. Can agricultural vulnerability be reduced through advanced monitoring of agricultural water consumptive use and improved drought estimation?

Image data helps capture and quantify the temperature differences between man-made and natural surfaces. JPL released a report highlighting a 10 June 2022 record high air temperature in Las Vegas, NV of 43 C (109 F) and the corresponding ground temperatures. For instance, asphalt surfaces reached 50 C (122 F), while suburban neighborhood surfaces reached 42 C (108 F) and green spaces measured 37 C (99 F).

As of August 2019, the Early Adopters Program has transitioned to the ECOSTRESS Community of Practice, with over 250 members.
