Wolf Fire, Los Padres National Forest (June 6-12, 2002):
As viewed by the FireMapper Thermal-imaging Radiometer aboard the Pacific Southwest Research Station's Airborne Sciences Aircraft
Images were collected and disseminated in part by satellite communications in near-real time from the PSW Airborne Sciences Aircraft. Shown is energy emitted from the ground as measured at thermal-infrared wavelengths by the PSW FireMapper system. Bright areas are very hot ground associated with active fire fronts. Images have been geographically referenced and are depicted on USGS 7.5-minute quadrangles, 1:100,000-scale topographic maps or on a digital elevation model derived from the Space Shuttle topographic mapping mission.

Color-coded surface temperatures associated with active or recent burning in the Wolf Fire, 6 June 2002.

Residual burning and spot fires at the Wolf Fire, 12 June 2002

Light gray tones are areas of ash warmed by solar heating. Dark gray tones are unburned vegetation. Red, orange, and yellow regions are residual burning. Latitude and longitude of hot spots may be obtained by opening the TIFF file in a suitable viewer such as Erdas Imagine. Postfire ash-surface temperatures may be indicative of the severity of burning.

After downloading a TIFF as a zip file, decompress it with WinZip (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).
