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...

On 04 December 2007, GOES-12 (the operational GOES-East satellite at 75º W longitude) experienced an anomaly in spacecraft attitude following a North-South station keeping maneuver; initial efforts to restore GOES-12 to a normal on-orbit mode were unsuccessful. As a result, GOES-10 (at 60º W longitude) was reassigned from South American... Read More
GOES-12 visible channel images (above) revealed an interesting wave structure along the top of an extensive stratus cloud deck that covered much of Iowa, southern Wisconsin, and northern Illinois on 20 November 2007. An AWIPS 4-panel image showing the MODIS and GOES-12 visible and IR window channels (below) demonstrated the... Read More
The large wildfires continued to burn across parts of southern California on 23 October 2007. AWIPS images of the GOES-11 imager visible channel (upper left panel), 6.7 µm water vapor channel (upper right panel), 10.7 µm IR channel (lower left panel), and the GOES-11 Sounder 4.0 µm IR channel (lower right panel)...
