Sentinel-1 change-screening methods and analytical releases for the Nepal disaster — REACH

Aim: Find the original Sentinel-1 change-screening methodology, versions and analytical releases.
Source and interface: IMPACT Initiatives/REACH — REACH resource repository
Search method: Search Nepal flash flood 2026 and Rasuwa through the repository's current native interface; retrieve all matching analytical records and linked methods; trace provider links from the existing HDX resource. Freeze the repository's actual syntax before execution. Exhaust the declared result set and all exposed pagination; retain original records and metadata. A provider limit or failed retrieval is a partial outcome, never a zero-result or complete run.
Criteria: Language unrestricted
Cloud cover unrestricted
Spatial extent WGS 84 [84.3976, 27.732, 85.5508, 28.35]
Time window 2026-06-27T00:00:00Z through 2026-09-06T22:37:19Z
Coverage: Event products: source-defined event release and historical references; spatial queries WGS84 [84.3976, 27.732, 85.5508, 28.35] from 2026-06-27 to frozen run start. Baselines retain stated source epochs.
Stopping rule: Exhaust all results and explicit product/metadata pagination for this declared interface; record unavailable or capped retrieval as such.
Result: Unavailable: the repository presented a sign-in form. No search result set could be retrieved; zero records here must not be interpreted as zero relevant resources. The existing REACH product was separately refreshed through HDX.
