Pines Fire, San Diego
County
10 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.
