Sources
Every figure on this platform traces back to a named source with its own licence, cadence and reliability. This page shows the live health of each one, and how each is attributed.
Risk model configuration: config/risk-model.json, version 2026.08.4. See the methodology page for what every weight in it means.

Update cadence
How often each source is refreshed in normal operation. A satellite detection can still be hours old when it arrives: polar-orbiting satellites pass a given point a handful of times a day, so "last fetched" and "last observed" are different things and both are shown above.
- NASA FIRMS
- Fetched every 20 minutes; new observations arrive with each satellite overpass (several per day), and NASA's near real time products themselves lag by around 3 hours.
- Open-Meteo weather
- Every 90 minutes across the UK grid and the most significant fire clusters.
- MET Norway weather
- Every 90 minutes at incident clusters outside the UK, giving wind direction and downwind sectors worldwide.
- EFFIS burned area
- Every 6 hours; the underlying Copernicus product itself updates roughly daily.
- EFFIS/GWIS fire danger
- Rendered directly from the EU map service on the live map; new forecast runs appear daily.
- Rain radar
- RainViewer composite, new frames roughly every 10 minutes.
- Context data
- Settlements, facilities and boundaries refresh daily; historical series are updated when their official sources publish.
Developers: every dataset on this site is available as JSON. See the API documentation.
