NASA's MISR Sees Wind-Whipped Fires in East Texas

As the remains of Tropical Storm Lee passed over Louisiana on Monday, Sept. 5, 2011, strong, gusty winds on the western side of the storm stoked fires throughout eastern Texas, which is already suffering from the worst one-year drought on record and the warmest month in Texas history.

The Multi-angle Imaging SpectroRadiometer (MISR) instrument on NASA's Terra spacecraft passed over the wildfires at 12:05 p.m. CDT on Sept. 5. At that time, temperatures were around 80 degrees Fahrenheit (27 degrees Celsius), with winds from the north gusting to 25 miles per hour (40 kilometers per hour). This image is a blend of data from MISR's vertical-viewing camera, which provides the sharpest view of surface features, and data acquired at a view angle of 70 degrees, which accentuates the appearance of smoke plumes generated by the fires. The Bear Creek Fire north of Marshall, near the top center of the image, is the largest fire in the scene. At the time this image was acquired, it had charred 30,000 acres and was 0 percent contained. To the west is the Diana Fire, just north of Longview, and the Henderson-502 Fire, northwest of Nacogdoches. The combined smoke from these two fires extends more than 171 miles (275 kilometers), passing over Lake Livingston into the northern outskirts of Houston. The city of Houston appears as the grayish area at the bottom of the image, to the left of Galveston Bay and the Gulf of Mexico.

This image covers about 275 miles (442 kilometers) in the north-south direction, and 199 miles (320 kilometers) in the east-west direction.

MISR was built and is managed by NASA's Jet Propulsion Laboratory, Pasadena, Calif., for NASA's Science Mission Directorate, Washington, D.C. The Terra satellite is managed by NASA's Goddard Space Flight Center, Greenbelt, Md. The MISR data were obtained from the NASA Langley Research Center Atmospheric Science Data Center. JPL is a division of the California Institute of Technology.
