ECOSTRESS Satellite Thermal Radiance Measurements at 70-Meter Resolution

ECOSTRESS Tiled Top of Atmosphere Calibrated Radiance Instantaneous L1C Global 70 m V002 provides at-sensor calibrated radiance values for five thermal infrared bands. Data is collected globally between 52° N and 52° S latitudes by the ECOSTRESS instrument on the International Space Station. The tiled product uses a modified Military Grid Reference System, dividing areas into 109.8 km square tiles with a 70-meter spatial resolution.

Use Cases

• Modeling plant water stress by analyzing calibrated radiance values across five thermal infrared bands.
• Generating cloud and water masks using the provided quality indicator layers for scene classification.
• Interpolating missing scan data in bands 1 and 5 using referenced machine learning techniques.
• Studying temporal changes in surface temperature by comparing radiance values for pixels at consistent locations within tiles.
• Investigating instrument artifacts by examining data for striping features in band 4 during February 2020.

Strengths

• Data provides five distinct thermal infrared bands operating between 8 and 12.5 µm.
• Spatial resolution is 70 meters per pixel, organized into consistent 109.8 km by 109.8 km tiles.
• Product contains 12 data layers, including radiance bands, quality indicators, and masks.

Limitations

• Known data acquisition gaps exist, including a period from May 2019 to April 2023 where some bands contain fill values.
• Instrument artifacts cause missing scan data or striping in specific bands, requiring interpolation.
• Geographic coverage is limited to latitudes between 52° N and 52° S, excluding polar regions.
