The “Lower North Fork Fire” near Aspen Park, Colorado began during the afternoon hours on 26 March 2012<\/strong><\/a> and rapidly expanded to over 4100 acres in size. 2 fatalities resulted from this fire, with over 900 homes being evacuated and at least 27 homes damaged or destroyed. The combination of strong southwesterly winds (gusting in the 35-50 mph range)<\/em> and very dry air (relative humidity values around 10%)<\/em> created an environment that was favorable for rapid wildfire growth. A comparison of McIDAS images of GOES-15 (GOES-West)<\/em> and GOES-13 (GOES-East)<\/em> 0.63 \u00c2\u00b5m visible channel data (above)<\/strong><\/em> showed the development of a large smoke plume with embedded pyrocumulus clouds.<\/p>\n

The corresponding series of GOES-15 and GOES-13 3.9 \u00c2\u00b5m shortwave IR images (below)<\/strong><\/em> revealed how quickly the fire “hot spot” (black to yellow to red color enhancement)<\/em> grew in size.<\/p>\n

An AWIPS comparison of a 1-km resolution POES AVHRR 3.7 \u00c2\u00b5m shortwave IR image with the corresponding 4-km resolution GOES-13 3.9 \u00c2\u00b5m shortwave IR image just after 02 UTC or 8 pm local time\u00c2\u00a0 (below)<\/strong><\/em> demonstrated the advantage of higher spatial resolution for more accurately identifying the location and areal coverage of the fire.<\/p>\n
