'''ECOSTRESS''' ('''Ecosystem Spaceborne Thermal Radiometer Experiment on Space Station''') is an ongoing [[scientific experiment]] in which a [[radiometer]] mounted on the [[International Space Station]] (ISS) measures the [[temperature]] of [[plant]]s growing in specific locations on [[Earth]] over the course of a [[solar year]]. These measurements give scientists insight into the effects of events like [[heat wave]]s and [[drought]]s on [[crop]]s.<ref name="clark">{{cite web|url=https://spaceflightnow.com/2018/06/28/commercial-spacex-cargo-capsule-readied-for-launch-friday/|title=Commercial SpaceX cargo capsule readied for launch Friday|last=Clark|first=Stephen|date=June 28, 2018|publisher=Spaceflight Now|access-date=2018-10-02}}</ref>

More specifically, ECOSTRESS seeks to answer three questions:{{fact|date=December 2025}} # How is the terrestrial [[biosphere]] responding to changes in water availability? # How do changes in the water stress experienced by [[diurnality|diurnal]] vegetation impact the global [[carbon cycle]]? # Can agricultural vulnerability be reduced through advanced monitoring of the consumptive use of water for [[agriculture]], and by improved estimation of the severity of [[drought]]s?

ECOSTRESS data has many other uses, such as comparing the temperatures of man-made surfaces (such as paved roads) and natural surfaces (such as prairie land) over time.{{fact|date=December 2025}}

The instrument that collects ECOSTRESS data is a multispectral, [[Thermal radiation|thermal]], [[infrared]] [[radiometer]]. It measures temperatures on the surface of the Earth, rather than [[surface air temperature]].<ref>{{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}}</ref><ref name="UQ">{{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}}</ref>

ECOSTRESS data is archived at the Land Processes Distributed Active Archive Center (LP DAAC),<ref>{{Cite web |title=LP DAAC - Homepage |url=https://lpdaac.usgs.gov |access-date=2022-10-27 |website=lpdaac.usgs.gov |language=en}}</ref> which is a data center managed by the [[United States Geological Survey]] (USGS).

The data collected is also published via the [[open-access]] TERN Data Discovery Portal in [[Australia]].<ref name="UQ"/>

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.<ref>{{cite web |title=Instrument |url=https://ecostress.jpl.nasa.gov/instrument |website=ECOSTRESS}}</ref> ECOSTRESS was delivered to the ISS by the [[SpaceX Dragon]] after a launch out of Cape Canaveral, Florida on 29 June 2018<ref name=":0">{{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}}</ref> The Dragon arrived at the space station on 3 July 2018.<ref name=":0"/> The radiometer was mounted on the station's [[Kibo (ISS module)|Kibo module]].

Image data is captured over the [[continental United States]] and target areas{{specify|date=December 2025}} every one to seven days.

=== Early adopters program === ECOSTRESS was the first Earth Venture Mission (EVM) to establish an early adopters program. The program grants its members access to provisional data, plus opportunities to collaborate with other ECOSTRESS users in a [[Slack (software)|Slack]] channel. As of August 2019, the Early Adopters Program has transitioned to the ECOSTRESS Community of Practice, with over 250 members.{{clarify|date=December 2025}}
