Black Mountain 2 Fire,
Missoula County, MT
23 August 2003
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 below). 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.
