Hold any mouse button down as you move the cursor across the large GOES-8 3.9 micron shortwave IR image; the smaller inset window shows the corresponding GOES-8 10.7 micron longwave IR image. The low stratus and fog (light gray enhancement) over southwestern Minnesota/northeastern South Dakota/southeastern North Dakota on the 3.9 micron IR image is not evident on the 10.7 micron IR image.
