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 Product Generation Executive (PGE) docker configuration and updates to the L1A_RAW_PIX software. Prior to October 2024, the field was not reliably populated; a separate 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 during the following periods: - September 29, 2018 – December 4, 2018 (primary MSU failure) - March 14, 2019 – May 14, 2019 (secondary MSU failure) - February 17, 2020 (instrument in SAFEHOLD mode) - Other early issues, including band 4 striping (February 8–16, 2020), 3-band mode limitations (May 15, 2019–April 28, 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.
• Geolocation considerations: While geolocation is improved in Version 3 tiled products (fixed MGRS grid), gridded products may reference legacy "GeolocationAccuracyQA" flags. Use "best" and "good" scenes for applications sensitive to precise positioning.
