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 (see chart
at left). 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.
