ECOSTRESS Tiled Top of Atmosphere Calibrated Radiance Instantaneous L1C Global 70 m V003

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 globally between 52° N and 52° S latitudes.

The ECOSTRESS Tiled Top of Atmosphere Calibrated Radiance Instantaneous Level 1C Global 70 m (ECO_L1CT_RAD) Version 3 data product provides at-sensor calibrated radiance values retrieved for five thermal infrared (TIR) bands operating between 8 and 12.5 µm. This tiled data product is generated from the ECO_L1CG_RAD Version 3 data product using a modified version of the Military Grid Reference System (MGRS), which divides Universal Transverse Mercator (UTM) zones into square tiles that are 109.8 km by 109.8 km with a 70 meter (m) spatial resolution.

The ECO_L1CT_RAD Version 3 data product contains 12 layers including radiance values for the five TIR bands, associated data quality indicators, a preliminary cloud mask, and a water body mask. Each variable is distributed as a separate Cloud Optimized GeoTIFF (COG) file.

Known Issues

  • Solar Array Obstruction: Some ECOSTRESS scenes may be affected by solar array obstructions from the ISS, potentially impacting data quality in obstructed pixels. The 'FieldOfViewObstruction' metadata field is reliably populated and accurate for all products generated on or after October 2024, following fixes to the PGE docker configuration and updates to the L1A_RAW_PIX software. Prior to October 2024, the field was not reliably populated; a list of confirmed affected scenes was maintained and is recommended for verifying historical data.
  • Historical acquisition gaps and anomalies (2018–2023): Irrecoverable data loss occurred due to Mass Storage Unit (MSU) failures, resulting in permanent gaps in the observational record where no ECOSTRESS data was acquired. Other early issues, including band 4 striping (Feb 2020), 3-band TES mode limitations (May 2019–April 2023), and noisy data periods (e.g., May–July 2025), have been mitigated through reprocessing, firmware updates, and instrument recovery. Version 3 products incorporate these improvements where data exists and are unaffected by ongoing issues, but the permanent historical gaps remain, and caution is advised for time-series analyses spanning affected periods.
