Dawn revealed the destruction of a deadly swarm of twisters that struck shell-shocked Oklahoma late Friday amid new fears about “life-threatening” flash floods.
NASA Spacecraft Captures Swath of Destruction from Deadly Oklahoma Tornado
The Newcastle-Moore EF-5 tornado ripped through central Oklahoma on May 20, 2013, killing 24 people and leaving behind more than $2 billion in damage. On June 2, 2013, the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) instrument on NASA’s Terra spacecraft captured this image showing the scar left on the landscape by the tornado’s deadly track. In this false-color image, vegetation is red, water is dark blue, roads and buildings are gray and white, and bare fields are tan. The tornado track crosses the image from left to right as indicated by the arrows. The image covers an area of 6 by 8.6 miles (9.6 by 13.8 kilometers), and is located at 35.3 degrees north latitude, 97.5 degrees west longitude.
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.
