NASA LANCE VIIRS flood products — Nepal tile h26v06 | Publicly Available Data Resources for the 2026 Nepal Glacier-Related Hazard Cascade

Resource details

Summary: NASA LANCE VIIRS near-real-time daily flood products for tile h26v06, covering 80–90° E and 20–30° N. Seven files were found in the available daily folders, beginning 30 August 2026. Earlier requested dates were unavailable on this server.
Review findings: Automated screening suggests potential eligibility. Official product documentation plus complete currently exposed daily folder listings provide Nepal tile file identities within the requested interval. Recent NRT holdings do not cover the complete requested June 27–search-date interval, including the initial event day. VIIRS source data are resampled to the output grid; output spacing is not native resolution. Cloud, cloud-shadow and short-lived flooding limitations require product quality assessment. Independent human screening and manuscript inclusion remain pending. All 7 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.
