Catalogue assessment and metadata evidence

Assessment recorded

Completed catalogue decisions are recorded separately from technical inspection and scientific validation. Access and metadata evidence retain their original dates and scope.

Completed catalogue assessment

Eligibility decision: Include · Include
Assessment date: 28 September 2026
Decision reason: The original source manifest, pinned file tree or text identifies this exact asset and its relation to an eligible resource. Retain as supporting quality or context layer; it is not a separate observation.

ISO spatial-coverage percentage describes product coverage, not the percentage of the event corridor observed.
Surface-water product; sensor-specific outputs are not harmonized. Cloud, shadow, terrain and QA layers must accompany interpretation.
Both inventory granules are June 27 baselines. Late-August processing does not make them post-event observations.
NASA documents free Earthdata registration. This review did not sign in or retrieve protected science files; anonymous denial is not a finding that the dataset is unavailable.
