An AWIPS image of POES AVHRR 3.7 \u00c2\u00b5m shortwave IR data (above)<\/strong><\/em> revealed a large number of fire “hot spots” (black to red to yellow pixels)<\/em> across much of eastern Kansas on 12 April 2011<\/strong><\/a>. The majority of these were grassland fires.<\/p>\n On the following day (13 April 2011<\/strong><\/a>), a well-defined area of dense smoke aloft could be seen stretching from Missouri into southwestwen Iowa on a MODIS 0.65 \u00c2\u00b5m visible channel image (below)<\/strong><\/em>.<\/p>\n MODIS 6.5 \u00c2\u00b5m visible channel image<\/p><\/div>\n ====================================<\/strong><\/p>\n GOES-13 0.63 \u00c2\u00b5m visible channel images (click image to play animation)<\/p><\/div>\n GOES-13 0.63 \u00c2\u00b5m visible images (above; click image to play animation)<\/strong><\/em> showed that the dense smoke feature moved very little during the day. An overlay of NAM12 850 mb winds (below)<\/strong><\/em> indicated that light southwesterly winds in the morning transitioned to a more organized southeasterly flow as a low-level cyclonic circulation moved southward across Nebraska into Kansas.<\/p>\n GOES-13 visible images + NAM12 850 mb winds<\/p><\/div>\n A MODIS true color<\/strong><\/a> Red\/Green\/Blue (RGB) image from the SSEC MODIS Today<\/strong><\/a> site (below; displayed using Google Earth)<\/em><\/strong> provided a better view of the smoke pall aloft as the northern end wrapped around the low-level cyclonic circulation.<\/p>\n<\/a><\/a><\/a>
