OPERA Sentinel-1 surface-water products — Nepal corridor, 27 June 2026 | Publicly Available Data Resources for the 2026 Nepal Glacier-Related Hazard Cascade

Resource details

Summary: OPERA Level 3 Dynamic Surface Water Extent products from Sentinel-1. Both observations returned for the Nepal corridor were acquired on 27 June 2026 and provide pre-event context. Processing in August does not establish event-period acquisition.
Review findings: Automated screening suggests potential eligibility. CMR collection-specific bbox/time queries exhausted at a short final page. Matching surface-water items can support event comparison with associated quality/context bands. Water presence alone is not an event flood anomaly. Optical cloud and terrain shadow may limit usable area. Collection validation does not establish event-site accuracy. Earthdata registration may be required for downloads. Independent human screening and manuscript inclusion remain pending. Both returned observations are from 27 June 2026; no post-event Sentinel-1 observation was returned by this query. All 14 asset metadata records were assessed in REV-20260907-ASSETS-001; 0 have flagged follow-up. Asset screening and field evidence are available in the metadata review export. This does not assign resource eligibility or manuscript inclusion.

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.
