Airborne images of the Willow fire in Southern California's San Bernardino County, taken September 1 from a NASA ER-2 airplane, show the blaze in wavelengths that are not visible to the naked eye. This set of infrared snapshots, taken by the Jet Propulsion Laboratory's Airborne Visible/Infrared Imaging Spectrometer, represents all of the infrared camera's 224 spectral channels, stacked in the image-cube format to depict the full AVIRIS measurement. The top and right panels show the full spectrum measured for each spatial element along the along the edge of the image. Spectroscopic or color analysis enables scientists to determine temperature variations, adjacent vegetation type and biomass, as well as the water content of leaves in the vegetation. These are important factors for understanding, controlling and extinguishing fires.

AVIRIS was designed, built and is operated by the Jet Propulsion Laboratory for NASA's Earth Science Enterprise. Data collection are made possible by NASA's ER-2 aircraft, which is housed at the Dryden Research Center at Edwards Air Force Base, CA. JPL is a division of the California Institute of Technology, Pasadena, CA.
