FIRMS

Near real-time active fire detections from NASA satellites, updated multiple times daily with 3–4 hour latency.

Forestry & Wildfire Management

Monitor forest cover, detect active fires, and plan wildfire prevention using satellite and sensor data.

Disaster Response

Support rapid disaster assessment, emergency management, and recovery efforts with real-time and historical hazard data.

Environmental Monitoring

Track environmental changes including deforestation, pollution levels, and ecosystem health using Earth observation data.

NASA FIRMS (Fire Information for Resource Management System) is the global standard for operational fire monitoring — and one of the few Earth observation products where the speed of delivery matters as much as the data itself.

With detections available within hours of a satellite overpass, FIRMS feeds directly into wildfire response coordination, air quality forecasting, agricultural burn tracking, and insurance damage assessment. The combination of near real-time delivery and a continuous archive stretching back to 2000 makes it both an operational tool and a research dataset for studying long-term fire regimes, deforestation patterns, and climate-driven shifts in fire activity.

What makes FIRMS particularly useful in a GIS context is that each fire detection is a geolocated point with rich attributes — brightness temperature, fire radiative power, confidence level, and acquisition time — so you can filter, aggregate, and overlay the data immediately.

Map fire detections against land cover to identify which ecosystems are burning, overlay with population and infrastructure layers for risk assessment, or aggregate by region and season to build fire frequency baselines. The point-based format also means FIRMS data loads cleanly into any GIS platform, including Atlas, without the processing overhead of raster satellite imagery.

Frequently Asked Questions

Typically 3–4 hours from satellite overpass to data availability. Most locations are observed 4+ times daily between the MODIS and VIIRS satellite instruments.

MODIS detects fires at 1km resolution with a continuous record since 2000. VIIRS detects at 375m resolution (since 2012) and catches approximately 3x more fires, including smaller and lower-intensity burns.

No. FIRMS provides point detections showing where fire was detected, not burned area boundaries. For fire perimeters, use MODIS burned area products or Sentinel-2 dNBR analysis.

Yes. Create a free account on FIRMS and define areas of interest to receive email notifications when fires are detected in those locations.

Yes. All FIRMS data is free, including the real-time Fire Map, CSV/Shapefile/KML downloads, email alerts, web services (WMS/WFS), and the REST API. No registration required for basic access.
