Current fire conditions are represented on the Fire M3 or Hotspot map. Each hotspot on the map is a satellite image pixel with infrared intensities typical of burning vegetation. A hotspot may represent one fire or be one of several hotspots representing a larger fire. Almost all hotspots indicate forest fires; however, not all fires can be identified from satellite images, usually because of cloud cover.M
The Fire M3 system (Fire Monitoring, Mapping and Modeling) uses low-resolution satellite imagery to identify and locate actively burning fires on a daily basis; to estimate annual area burned; and to model fire behavior, biomass consumption, and carbon emissions from fires.
