Curve Fire, Angeles
National Forest
7 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 (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.

(or your favorite ZIP utility) and the TIFF will be viewable in
WangIMG or other graphics viewer. Included are the auxiliary files
necessary for proper geo-referencing (if the viewer has that capability).
