Blowing dust from Mexico across Texas and New Mexico
McIDAS images of GOES-13 0.63 Âµm visible channel data (above) revealed several plumes of blowing dust originating in northern Mexico, which then drifted northeastward across parts of Texas and New Mexico during the afternoon hours on 28 November 2010. At El Paso, Texas (located at the center of the image), winds gusted to 52 mph, and surface visibility was reduced to 2.5 miles due toÂ blowing dust. Farther to the east, winds gusted to 64 mph at Guadalupe National Park.
A comparison of the MODIS 0.65 Âµm visible channel image and the corresponding 11.0 Âµm – 12.0 Âµm IR brightness temperature difference image (below) showed a signal where the airborne blowing dust was the most concentrated (yellow enhancement).
AWIPS images of MODIS 0.65 Âµm visible channel data and MODIS 11.0 Âµm IR channel data (below) showed that many of the larger plumes exhibited a slightly cooler (lighter gray) appearance on the IR image.
