Aerial view of fire. Temperatures associated with fire are colored in yellow through purple.
Background temperature are colored in black and white. The full temperature scale is shown on the left. Note that yellow can both represent hot ash or a hot section of bare ground unrelated to the fire.
These images depict approximate fireline locations in color-coded pixels (see chart at left). Use the map backgrounds as a general location guide, and look for recognizable terrain features or landmarks on the imagery itself for relative positioning of hotspots. Bodies of water, street grids, open fields, highways, ridgelines and stream courses show up well in this imagery.
Images were collected via fixed-wing aircraft. The thermal-imaging radiometer used measures emitted long-wave thermal-infrared radiation, which readily penetrates smoke. False-color images shown here depict the apparent surface temperature (in Celsius) as estimated from measured radiance and a simple black-body model. Warmer tones represent recent or active combustion; areas of light yellow represent cooling ash or warm bare ground. Lower temperatures associated with unburned forest and cool ground are shown in black and white. The full temperature scale can be found on the left. Images have been geographically referenced.
