Surface temperatures as estimated from radiance measured at 11.9 micrometers wavelength in the thermal infrared by the PSW FireMapper system. 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.
