Williams Fire, Angeles National Forest
26 September 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.
