NASA Instrument Reveals Extent of Largest Colorado Fire

Press Release From: Jet Propulsion Laboratory
Posted: Wednesday, June 19, 2002

Thousands of acres of burned vegetation, along with recent hotspots, are visible in a new image of Colorado's worst forest fire taken by NASA's Advanced Spaceborne Thermal Emission and Reflection Radiometer (Aster).

Started on June 8, the Hayman forest fire continues to burn in the Pike National Forest, 57 kilometers (35 miles) south-southwest of Denver, Colo. According to the U.S. Forest Service, the fire has consumed more than 100,000 acres.

The image is available at: .

Acquired Sunday morning, June 16, 2002, the Aster image shows active fires in red. The dark blue area is burned vegetation, and the green areas are healthy vegetation. Clouds are white. The blue cloud at the top center is smoke. The image covers an area of 32.2 by 35.2 kilometers (20 by 21.8 miles).

Aster is one of five Earth-observing instruments launched in December 1999 on NASA's Terra satellite. 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 will image Earth for the next six years to map and monitor the planet's changing surface. Japan's Ministry of Economy, Trade and Industry built the instrument. NASA's Jet Propulsion Laboratory, Pasadena, Calif., is responsible for the American portion of the joint U.S./Japan science team that validates and calibrates the instrument and the data products.
