ECOSTRESS Geolocation Daily L1B Global 70m V001

ECOSTRESS Version 1 geolocation data from NASA provides latitude, longitude, and geometry information for thermal radiance pixels measured by the instrument on the International Space Station. The data covers a global swath between 52 degrees north and south latitude, with a spatial resolution of 70 meters. Forward processing for this version was discontinued on January 6, 2025, and users are encouraged to transition to Version 2 products.

Use Cases

• Georeferencing ECOSTRESS radiance and derived data products based on the provided latitude and longitude variables.
• Analyzing solar and view geometry for thermal imagery based on the included geometry information.
• Assessing land-water pixel fractions for surface type classification in thermal studies.
• Correcting ISS ephemeris and attitude data through image matching with a Landsat-derived ortho-base.

Strengths

• Geolocation accuracy is better than 50 meters when image matching correction is successful, as indicated by the 'L1GEOMetadata/OrbitCorrectionPerformed' field being 'True'.
• Data provides essential variables for georeferencing multiple ECOSTRESS data products (ECO1BRAD, ECO2LSTE, etc.).
• Collected globally between 52 degrees N and 52 degrees S latitudes from the International Space Station.

Limitations

• In uncorrected scenes where image matching failed, geolocation error can be up to 7 kilometers.
• There were known data acquisition gaps due to instrument anomalies, notably from May 15, 2019, through April 28, 2023, where some bands contain fill values.
• This is a Version 1 product whose forward processing was discontinued on January 6, 2025.
