Fire Danger Forecast: Daily Fire Weather Index from ECMWF and NASA Models

Global daily fire danger indices are provided as continuous raster GeoTIFFs. The data is produced by the Copernicus organization using the ECMWF and NASA Geos-5 models, with the Fire Weather Index mapped into six classes including 'Very Extreme'. The dataset was last updated on 2026-05-21.

Use Cases

• Generate daily wildfire risk maps based on the Fire Weather Index (FWI) classes.
• Compare fire danger forecasts from the ECMWF (~8 km) and NASA Geos-5 (~28 km) models.
• Analyze trends in 'Very Extreme' fire danger conditions, introduced for Mediterranean summers.
• Integrate continuous raster fire danger data into geospatial analysis platforms.

Strengths

• Provides daily forecasts, enabling near-real-time monitoring.
• Uses two established models: ECMWF at ~8 km resolution and NASA Geos-5 at ~28 km resolution.
• Includes a specific 'Very Extreme' class for FWI values above 70, introduced in June 2021.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• The exact spatial and temporal coverage is not specified in the provided metadata.
