The plumes of airborne aerosols exhibited a lighter gray “hazy” appearance on the visible image (and to a lesser extent on the “cirrus detection” image, due to that channel’s sensitivity to particles that scatter light)<\/em>.<\/p>\n

In addition, there was a small cluster of hot MODIS 3.7 \u00c2\u00b5m IR pixels with a maximum temperature of 46\u00c2\u00ba C located just northwest of Hobbs, New Mexico (station identifier KHOB),<\/em> due to a grass fire that was burning in that area (MODIS 3.7 \u00c2\u00b5m image<\/a><\/strong>) — and 250-meter resolution MODIS true color imagery (below)<\/strong><\/em> confirmed the presence of a lighter-colored smoke plume embedded within the longer orange-colored blowing dust plume. The burn scar from this fire was clearly evident on MODIS true color imagery (viewed using Google Earth)<\/a><\/strong> on the following day (located between Lovington and Maljamar, New Mexico)<\/em>.<\/p>\n

The strong winds (which gusted as high as 71 mph at Tatum, New Mexico)<\/em> were producing mountain waves immediately downwind of the higher terrain in the “Big Bend region” of Texas — a comparison of 1-km resolution MODIS 6.7 \u00c2\u00b5m and 4-km resolution GOES-12 6.5 \u00c2\u00b5m water vapor images (below)<\/strong><\/em> demonstrated the value of better spatial resolution for detecting such mesoscale phenomena.<\/p>\n
