A comparison of AWIPS images of the GOES-12 3.9µm and the MODIS 3.7µm “shortwave IR” channels (above) revealed that numerous small fires were burning across parts of eastern Kansas and northeastern Oklahoma during the afternoon of 06 April 2008. Note how the 1-km resolution MODIS imagery did a better job... Read More

Winds up to 60 mph associated with a strong cold front moving across the mountains of northern Mexico on 18 March 2008 were creating areas of blowing dust and sand, as well as fostering an environment favorable for wildfire activity. A comparison of AWIPS images of the MODIS visible channel, 1.3µm “cirrus detection” channel, 3.7µm “shortwave IR” channel, 11.0µm “IR window” channel, and 6.7µm “water vapor” channel... Read More

[Image source: Liam Gumley, SSEC/CIMSS] A comparison of two consecutive MODIS true color images from the same day (viewed using Google Earth, above) reveals that numerous small fires developed (and produced smoke plumes) within a relatively short amount of time across the southeastern US on 12 March 2008. The satellite overpass... Read More
