MODIS 3.7 \u00c2\u00b5m shortwave IR, 11.0 \u00c2\u00b5m IR, and Land Surface Temperature product<\/p><\/div>\n

As noted on the AccuWeather WeatherMatrix blog<\/a><\/strong>, some locations in far eastern Colorado and far western Kansas experienced a “heat burst” as dry convection passed across the region overnight. AWIPS images of the 04:35 UTC (10:35 pm local time)<\/em> MODIS 3.7 \u00c2\u00b5m shortwave IR, MODIS 11.0 \u00c2\u00b5m IR, and MODIS Land Surface Temperature (LST) product (above)<\/em><\/strong> revealed the isolated pocket of warm temperatures (darker orange color enhancement: as high as 24\u00c2\u00ba C \/ 75.2\u00c2\u00ba F<\/strong> on the shortwave IR image, 21.5\u00c2\u00ba C \/ 70.7\u00c2\u00ba F<\/strong> on the IR image, and 25.4\u00c2\u00ba C \/ 78.7\u00c2\u00ba F<\/strong> on the LST product)<\/em> just northwest of Burlington, Colorado (station identifier KITR),<\/em> in the wake of the passing convection (which exhibited cloud top IR brightness temperatures as cold as -36\u00c2\u00ba C<\/strong>, darker blue color enhancement)<\/em>. Around the time of the MODIS images, the surface air temperature at Burlington<\/a><\/strong> had abruptly risen to 89\u00c2\u00ba F \/ 32\u00c2\u00ba C<\/strong> with wind gusts to 53 knots (61 mph)<\/a><\/strong>.<\/p>\n

A comparison of the 1-km resolution MODIS 11.0 \u00c2\u00b5m IR image with the corresponding 4-km resolution GOES-13 10.7 \u00c2\u00b5m R image (below)<\/em><\/strong> demonstrated the dramatic improvement in feature detection with higher spatial resolution. Parallax error associated with the high viewing angle of the geostationary GOES-13 satellite was also obvious in the image comparison.<\/p>\n

MODIS 11.0 \u00c2\u00b5m IR and GOES-13 10.7 \u00c2\u00b5m IR images<\/p><\/div>\n

An animation of the GOES-13 10.7 \u00c2\u00b5m IR images (below)<\/em><\/strong> showed the warm heat burst signature (the pocket of darker orange colors)<\/em> migrating eastward into western Kansas, where the surface air temperature at Goodland<\/a><\/strong> (station identifier KGLD)<\/em> later rose to 92\u00c2\u00ba F \/ 33\u00c2\u00ba C<\/strong> at 06:00 UTC (Midnight local time)<\/em>. Note that there no cloud-to-ground lightning strikes associated with the convection that produced the heat burst.<\/p>\n

The heat burst signature was even evident on the 10-km resolution GOES-13 sounder Skin Temperature derived product image (below)<\/em><\/strong>, with a maximum skin temperature value of 21.5\u00c2\u00ba C \/ 70.7\u00c2\u00ba F<\/strong> just to the northwest of Burlington, Colorado at 05:00 UTC (11:00 pm local time)<\/em>.<\/p>\n
