\"GOES-12<\/a><\/p>\n

The large “Angora wildfire”<\/strong><\/em><\/a> began to burn just south of Lake Tahoe in California sometime after 21:00 UTC (1:00 PM local time) on 24 June 2007<\/strong><\/a>, eventually destroying 254 homes and burning 3100 acres. Images of the 3.9\u00c2\u00b5m InfraRed (IR) and visible channels from GOES-12 (above; Java animation<\/a>)<\/strong><\/em> and GOES-11 (below; Java animation<\/a>)<\/strong><\/em> revealed a large “hot spot” (black pixels)<\/em> associated with this fire, as well as a long smoke plume that spread quickly northeastward during the afternoon hours. Dark IR “hot spots” were first evident on GOES-12 imagery at 21:32 UTC and on GOES-11 imagery at 21:41 UTC, with a “processed fire” (red pixel)<\/em> showing up on the GOES-11 Wildfire ABBA product<\/strong><\/a> at 22:00 UTC. Note that the hot fire saturated the 3.9\u00c2\u00b5m detectors on GOES-12, causing the temperature to “roll over” and be falsely displayed as very cold (white)<\/em> pixels. The saturation temperature of the GOES-11 3.9\u00c2\u00b5m detectors (338.8\u00c2\u00ba K \/ 66\u00c2\u00ba C \/ 150\u00c2\u00ba F)<\/strong> was reached as early as 22:30 UTC (2:30 PM local time).<\/p>\n

\"GOES-11<\/a><\/p>\n

The majority of the smoke was transported rapidly northeastward between Reno, Nevada (KRNO) and Fallon, Nevada (KNFL) by strong winds aloft; however, GOES-12 visible imagery indicated that some smoke at lower altitudes was curving southward away from the main plume and moving toward Fallon (and areas south of Fallon) after about 00:00 UTC on 25 June. The surface meteorogram from Fallon (below)<\/strong><\/em> indicates that surface visibility there dropped from 10 miles to 6 miles around 02 UTC as this smoke began to move into the area.<\/p>\n

\"Fallon<\/a><\/p>\n

The fire continued to burn for several days; a Terra MODIS true color image from 26 June (below)<\/strong><\/em> shows a smaller smoke plume that was continuing to drift northward across the lake.<\/p>\n
