ECOSTRESS: Top of Atmosphere Calibrated Radiance at 70m Resolution

ECOSTRESS Swath Top of Atmosphere Calibrated Radiance Instantaneous L1B Global 70 m V002 is a NASA data product providing at-sensor calibrated radiance values for five thermal infrared bands and digital numbers for a shortwave infrared band. The instrument is attached to the International Space Station and collects data globally between 52° N and 52° S latitudes. The data is distributed in HDF5 format and requires a separate geolocation product for spatial referencing.

Use Cases

• Modeling plant water use and stress based on thermal infrared radiance measurements.
• Analyzing land surface thermal properties based on calibrated radiance from five TIR bands.
• Investigating shortwave infrared reflectance characteristics using the provided SWIR band digital numbers.
• Studying global temperature patterns within the 52° N to 52° S latitude range covered by the instrument.

Strengths

• Provides calibrated radiance for five thermal infrared bands between 8 and 12.5 µm.
• Offers a variable spatial resolution between 70 meters and 90 meters.
• Data is collected from the International Space Station, providing a unique orbital perspective.

Limitations

• The radiance data product does not contain geolocation information and requires a separate file for georeferencing.
• Known data acquisition gaps exist, including a period from May 2019 to April 2023 where only TIR bands 2, 4, and 5 were downloaded.
• Column-level documentation is absent; field semantics must be inferred after download.
