ECOSTRESS (ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station)
ISS-hosted multispectral thermal infrared radiometer using the PHyTIR instrument, with five TIR bands from 8-12.5 um plus a 1.6 um geolocation/cloud band, approximately 70 m native pixels and a 384 km swath.
ECOSTRESS is the ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station, implemented as the PHyTIR radiometer mounted on the International Space Station Japanese Experiment Module Exposed Facility [1]. It is a passive multispectral thermal infrared scanner with five TIR bands spanning 8 to 12.5 um and a 1.6 um band used for geolocation and cloud screening [1][2]. The instrument samples approximately 69 by 38 m nadir pixels, often rounded to about 70 m, across a 384 km swath at the ISS orbital height [1]. ECOSTRESS produces temperature and emissivity imagery for evapotranspiration, plant water stress, wildfire, and volcanic hazard applications [3]. Operations were approved through FY2026 with possible continuation to FY2029, subject to the 2026 Senior Review [3].
