MODIS 3.7 \u00c2\u00b5m shortwave IR images<\/p><\/div>\n

Wildfire activity was beginning to increase across parts of Quebec, Canada on 24 June 2009<\/a><\/strong> — and AWIPS images of the MODIS 3.7 \u00c2\u00b5m shortwave IR channel (above)<\/em><\/strong> revealed a number of large fire “hot spots” (red to yellow color enhancement)<\/em> that were increasing in areal coverage between 16:29 UTC and 18:14 UTC.<\/p>\n

According to the CIMSS Wildfire ABBA<\/a><\/strong> product (below),<\/em><\/strong> some of these fires were hot enough to saturate the 3.9 \u00c2\u00b5m shortwave IR sensor on GOES-12 (yellow fire pixels)<\/em>.<\/p>\n

In addition, false color Red\/Green\/Blue (RGB) images using the MODIS visible channel, the 2.1 \u00c2\u00b5m near-IR “snow\/ice” channel, and the 3.7 \u00c2\u00b5m shortwave IR channel (below)<\/em><\/strong> also showed that during the 105 minutes between the 2 MODIS images there was a significant amount of southward displacement to the ice that remained in the northern half of James Bay — ice in the bay (as well as glaciated ice crystal clouds)<\/em> exhibited varying shades of pink in the RGB image, in contrast to areas of open water (darker blue colors)<\/em> or supercooled water droplet clouds (varying shades of white)<\/em>.<\/p>\n
