The spread of the forest fire in Valle Nuevo National Park near Costanza, Dominican Republic that started nearly two weeks ago was considerably contained by Aug. 5, 2014, according to the Environment Ministry. An appeal by the Dominican government to the United States for assistance was answered with funds and equipment. The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) instrument on NASA's Terra spacecraft captured this thermal infrared view of the region on Aug. 5, 2014. Active hot spots of the fire are shown in yellow, healthy vegetation is depicted in red, and the burned areas are dark gray. The image is located at 18.8 degrees north, 70.7 degrees west, and covers an area of 12.1 by 12.7 miles (19.5 by 20.4 kilometers).

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 Dec. 18, 1999, on Terra. 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 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 NASA's Jet Propulsion Laboratory, Pasadena, Calif. The Terra mission is part of NASA's Science Mission Directorate, Washington, D.C.
