Two new sources of Google Earth satellite imagery are now available from SSEC: AVHRR images from the NOAA operational polar orbiting satellites, and MODIS images from the NASA Terra and Aqua satellites. An example of the AVHRR “false color” imagery (above) zooms in to show the deep snow cover that existed over much of the Upper Midwest... Read More
AWIPS images of the MODIS visible and 1.6 µm “snow/ice channel” images from 17 December 2007 (above) demonstrate the utility of the snow/ice channel for helping to identify areas of thin supercooled water droplet stratus clouds that exist over a snow-covered satellite scene (this MODIS imagery was mentioned in the NWS Milwaukee/Sullivan...

AWIPS images of the GOES-10 10.7 µm IR channel (above) showed a patch of low-level stratus cloud drifting north-northeastward across Iowa, Minnesota, and Wisconsin on 10 December 2007. Note how the tops of the cloud feature appeared warmer (darker gray enhancement) than the adjacent cloud-free (but snow-covered) areas; the term... Read More
The MODIS true color image (above) centered over northeastern Wisconsin on 03 December 2007 is from the SSEC MODIS Today site. Note the narrow white swath running from southwest to northeast near the center of the image — this feature is the... Read More
