How WildfireSignal Works
WildfireSignal brings together public wildfire data from multiple sources and turns it into clear U.S. and international views. Official incident reports, published fire perimeters, Copernicus burned-area data and NASA satellite heat are kept distinct so readers can see what each source actually represents.
Collect
WildfireSignal gathers public wildfire data from several sources, including NASA FIRMS satellite detections, U.S. official incident and perimeter feeds, Canadian and Australian fire agencies, and Copernicus GWIS where supported. Each source is collected separately so its original meaning is preserved.
Organize
Data from different agencies and systems is standardized for display and comparison. Official incidents, published fire perimeters, Copernicus burned-area data and satellite heat remain separate. A satellite heat signal is never automatically treated as a confirmed wildfire.
Track Reported Changes
WildfireSignal retains data snapshots over time so changes in reported acreage, containment and active incident status can be followed as agencies publish updates. This shows how reported conditions are changing, not just what the latest number says.
Present clearly
WildfireSignal presents the data through the live map, national briefings, state and country pages, and individual fire pages. Each view identifies the source and type of information so official reports, Copernicus fire areas and satellite heat are not blurred together.
What WildfireSignal Does Not Claim
Satellite heat detections are not automatically confirmed wildfires. Reported acreage, containment, published fire perimeters and burned-area estimates can change as agencies and source systems publish new information.
WildfireSignal is designed for situational awareness. It is not an emergency-alerting service and should not replace evacuation orders, warnings or instructions from local authorities.
