Harrington Ridge Fire, Idaho County, Idaho

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.

Helpful hints for 3D viewing-

Click on the 'fit' button (lower right) to fit the image to your browser window.

For good rotation of the 3D image, set the 'walk' or 'fly' mode in combination with the 'plan' movement option to move in closer (using the mouse); then switch to the 'study' mode and the 'turn' movement option to rotate the scene (using the mouse).
