Station Fire Burns in the San Gabriel Mountains Above Los Angeles

On September 15, 2009, the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) instrument on NASA’s Terra spacecraft captured this simulated natural color image of the Station fire burning in the San Gabriel Mountains above Los Angeles. The fire started on August 26 near NASA’s Jet Propulsion Laboratory, and soon grew to become the largest fire in Los Angeles County history. Three weeks after its start, the fire had consumed more than 160,000 acres of forest (approximately 251 square miles), leaving behind a charred, blackened landscape, as it spread eastward. As of the date of this image, containment stood at 91 percent of its perimeter. The large dark gray area dominating the image is the evidence of forest and chaparral destruction in the eastern half of the burn area.

With its 14 spectral bands from the visible to the thermal infrared wavelength region and its high spatial resolution of 15 to 90 meters (about 50 to 300 feet), ASTER images Earth to map and monitor the changing surface of our planet. ASTER is one of five Earth-observing instruments launched December 18, 1999, on NASA's Terra satellite. The instrument was built by Japan's Ministry of Economy, Trade and Industry. A joint U.S./Japan science team is responsible for validation and calibration of the instrument and the data products.

The broad spectral coverage and high spectral resolution of ASTER provides scientists in numerous disciplines with critical information for surface mapping and monitoring of dynamic conditions and temporal change. Example applications are: monitoring glacial advances and retreats; monitoring potentially active volcanoes; identifying crop stress; determining cloud morphology and physical properties; wetlands evaluation; thermal pollution monitoring; coral reef degradation; surface temperature mapping of soils and geology; and measuring surface heat balance.

The U.S. science team is located at JPL, Pasadena, Calif. The Terra mission is part of NASA's Science Mission Directorate.
