MODIS true color images (viewed using Google Earth, above) showed that significant snow cover still remained over parts of the Upper Midwest region (especially across northeastern Ohio) on 11 March 2008. With the highway overlays removed, you can better see that several of the smaller towns across northeastern Ohio have a slightly darker... Read More

Several large wildfires began to burn across parts of western Texas (and also southeastern New Mexico) late in the day on 25 February 2008, as seen by the large number of fire “hot spots” (black to red pixels, with red being the hottest temperatures) on GOES-12 3.9 µm “shortwave IR” images (above)....

GOES-12 visible channel imagery (above) displayed several different lake-effect snow (LES) producing mechanisms across the Great Lakes on 20 February 2008: multiple LES bands over Lake Superior, meso-vorticies over both Lake Michigan and Lake Huron, and a single LES band over Lake Ontario. Even though the Great Lakes water temperatures were getting... Read More

AWIPS images of the MODIS visible channel, the 1.6µm near-IR “snow/ice channel”, and the 11.0µm “IR window” channel (above) revealed a large patch of supercooled water droplet stratus cloud (and/or fog) over northeastern Utah on 19 February 2008. This stratus/fog cloud feature was confined to the lower elevations (AWIPS topography image | Johns Hopkins topography image) where... Read More
