ECOSTRESS: At-sensor Radiance for Plant Temperature and Water Stress

ECOSTRESS At-sensor Calibrated Radiance Daily L1B Global 70m V001 provides calibrated radiance values from the International Space Station. This decommissioned Level 1B product contains five thermal infrared bands (8-12.5 microns) and a shortwave infrared band, with a variable spatial resolution of 70-90 meters. The data is provided as swath data without geolocation, requiring a separate georeferencing product for spatial analysis.

Use Cases

• Estimating plant water stress based on thermal infrared radiance values.
• Analyzing spatial patterns of plant temperature at a sub-100 meter resolution.
• Calibrating or validating higher-level ECOSTRESS products using the at-sensor radiance.
• Studying diurnal or seasonal plant thermal responses using the time-series data from the ISS orbit.

Strengths

• Provides data from a unique sensor on the International Space Station, offering a specific observation geometry.
• Covers a broad latitudinal range between 52 degrees N and 52 degrees S.
• Contains five calibrated thermal infrared bands and one shortwave infrared band, allowing for multi-spectral thermal analysis.

Limitations

• The dataset was decommissioned on May 21, 2025, and users are directed to newer Version 2 products.
• Data lacks embedded geolocation information, requiring a separate file (ECO1BGEO) for spatial reference, which complicates analysis.
• Spatial resolution is variable (70-90m) across the swath, and there is a known data acquisition gap mentioned but not detailed.
