Controlled open-data source inventory

Model-derived river-discharge evidence near configured coordinates

• • Returns the largest river represented within approximately 5 km of a coordinate.
• • Model output is not a physical gauge reading.
• • The connector requests 90 past days and 14 source-forecast days.
• • Ensemble statistics are available for forecast periods and not consolidated historical data.
• • Historic/current and source-forecast values are retained as separate phases.
• • Not admitted for Strategic Signal, Risk Clock, Impact Window, or Live Outlook activation.

Current and forecast meteorological context

• • Model-derived weather context is not a substitute for validated local stations.
• • Forecast values are not observations and remain separately classified.

On-demand historical meteorological evidence

• • Used on station detail pages to provide historical context, not a production seasonal baseline.
• • Repeated requests to the same grid cell may be rate-limited by the provider.

Regional disaster context for analyst awareness

• • Requires a pre-approved appname configured through RELIEFWEB_APPNAME.
• • Context records are not environmental observations.
• • Context records cannot activate Strategic Signals or Risk Clock states.
• • Original information-partner rights and attribution remain applicable.

Regional natural-event metadata for contextual awareness

• • EONET is a metadata repository for natural events, not a hydrological observation network.
• • The connector uses a regional bounding box and a 90-day context window.
• • Event metadata cannot activate Strategic Signals, Risk Clock states, or emergency alerts.

Regional seismic context from the FDSN event service

• • The connector requests magnitude 2.5+ events for the last 30 days within the initial regional bounding box.
• • Catalog records do not establish hydrological causality or infrastructure impact.
• • Records cannot activate Strategic Signals, Risk Clock states, or emergency alerts.

Time-controlled satellite imagery evidence through public WMTS services

• • Daily composite imagery may include cloud, acquisition gaps and variable observation timing.
• • Visual imagery is evidence for review and is not an automatic water-extent, flood, severity or Strategic Signal calculation.
• • The package references WMTS tiles but does not archive the image tiles in Environmental Memory.

Public discovery of candidate Sentinel-1 and Sentinel-2 products

• • Catalogue records do not mean a product was downloaded, processed, cloud-masked or analysed.
• • Product licensing, access and analytical admission remain separate controlled steps.

Basemap and non-authoritative geographic context

• • Basemap features are context only and do not constitute the validated production geographic package.
