Pines Fire, San Diego
County
3 August 2002
As viewed by the FireMapper
Thermal-Imaging Radiometer
Images were collected from the PSW Airborne
Sciences Aircraft and disseminated in part by satellite
communications in near-real time. FireMapper measures the
radiance of emitted thermal-infrared light, which readily
penetrates smoke. False-color images shown here depict the
apparent surface temperature (in Celsius) as estimated from
radiance and a simple black-body model. Warmer tones represent
recent or active combustion; areas of gray are cooling ash
or warm bare ground. Low temperatures of unburned forest
and cool ground are shown in green. Images have been geographically
referenced. Vertical exaggeration in 3-d views is 1.5 to
one unless otherwise noted.
