Surface temperatures as estimated from radiance measured at 8-12 micrometers wavelength in the thermal infrared by a FireMapper 2 radiometer. A color scale is shown at lower right. Warmer tones (red, orange, yellow) represent recent and active combustion; surrounding landscape temperatures where measured are shown in tan shades. Large reaches of higher temperature behind a fire front are typically associated with heavy fuel loading.  Imagery was collected in association with Kolob Canyon Air Services and San Diego State University.  Use the tool bar at the bottom of the image to zoom and pan.
