Moose-Wasson Fire, southern Lincoln Complex, MT
20 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.

LINCOLN COMPLEX, Helena National Forest. A Type 1 Incident Management Team (Studebaker) is assigned. This complex is comprised of the Moose-Wasson and Snow-Talon fires, ten miles west of Lincoln, MT. Both fires experienced a significant increase in fire behavior.
Multiple tree torching and short range spotting were observed. Structure protection is in place for 150 residences and 20 commercial properties.
