EARTH OBSERVATION
Satellite and Radar Data Reveal Damage Track of Alabama Tornadic Thunderstorms
by Staff Writers
Birmingham AL (SPX) Jun 01, 2011


Radar image of tornado near Tuscaloosa, Ala., on April 27, 2011. (NASA/SPoRT). To view a larger version of this image please go here.

This image shows the radar reflectivity from the National Weather Service Doppler Radar in Birmingham, Ala. at 5:10 p.m. CDT on April 27, 2011, as a supercell thunderstorm moved across the city.

The radar reflectivity is overlaid upon Advanced Spaceborne Thermal Emission and Reflection Radiometer, or ASTER, satellite data acquired on May 4, 2011, showing the damage track resulting from for the EF-4 tornado associated with the storm as it passed through the city and continued northeast toward Birmingham, Ala.

The complex pattern of ASTER data indicate variability in land use characterized by colors in this three-channel composite. Here, the ASTER data shows the tornado damage scar - aqua in color - left by the violent tornado as damage disrupts other, more typical land use patterns, while radar data shows the classic "hook echo" signature associated with the rotating storm updraft.

On the lower end of the hook is a round region of enhanced radar reflectivity - near the Interstate 359 marker - associated with the surface debris lofted by the tornadic winds.

This "debris ball" signature corresponds to the ASTER tornado damage track in this and subsequent radar images.

EARTH OBSERVATION
New NASA Map Reveals Tropical Forest Carbon Storage
Pasadena CA (JPL) Jun 01, 2011
A NASA-led research team has used a variety of NASA satellite data to create the most precise map ever produced depicting the amount and location of carbon stored in Earth's tropical forests. The data are expected to provide a baseline for ongoing carbon monitoring and research and serve as a useful resource for managing the greenhouse gas carbon dioxide. The new map, created from ground- ... read more
