    • ECOSTRESS Evaporative Stress Index dis-ALEXI Daily L4 CONUS 70 m V001

    Metadata Updated: December 6, 2023

    The ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station (ECOSTRESS) mission measures the temperature of plants to better understand how much water plants need and how they respond to stress. ECOSTRESS is attached to the International Space Station (ISS) and collects data over the conterminous United States (CONUS) as well as key biomes and agricultural zones around the world and selected FLUXNET (http://fluxnet.fluxdata.org/about/) validation sites. A map of the acquisition coverage can be found on the ECOSTRESS website (https://ecostress.jpl.nasa.gov/science).

    The NASA Jet Propulsion Laboratory (JPL) ECO4ESIALEXI Version 1 data product provides the Evaporative Stress Index (ESI), which is computed from clear-sky estimates of the relative daily evapotranspiration (ET) fraction: ESI = ET/ETo, where ET is ETdaily from the ECOSTRESS Level 3 product and ETo is the reference ET. A description of the major components of the ECOSTRESS algorithm implemented in Version 1 of the Atmosphere Land Exchange Inverse (ALEXI) Disaggregation algorithm (DisALEXI) ESI code is provided in the Algorithm Theoretical Basis Document (ATBD) (https://lpdaac.usgs.gov/documents/1002/ECO4ESIALEXI_ATBD_V1.pdf). ESI applications include indicating agricultural drought and observing vegetation stress. ECO4ESIALEXI is available for CONUS at 70-meter (m) pixel resolution.

    The ECO4ESIALEXI Version 1 data product contains layers of daily evaporative stress index, evaporative stress index uncertainty, and associated quality flags. A low-resolution browse is also available showing daily ESI as a stretched image with a color ramp in JPEG format.
