A comparison of GOES-12 and GOES-13 visible images (above) showed a long lake-effect cloud band that was oriented generally north-to-south across Lake Michigan on 20 January 2009. Convergence of surface winds was helping to sustain the cloud band over the lake, which... Read More

A strong “Alberta Clipper” system ushered in some of the coldest air of the 2008/2009 winter season on 12 January 2009 — in fact, it was so cold that AWIPS images of the GOES-12 10.7 µm IR channel data (above) showed that surface brightness temperatures as cold as -20º to -40º C... Read More

AWIPS images of the MODIS Sea Surface Temperature (SST) product at 16:22 UTC on 08 January 2009 and the closest corresponding RTG-SST model analysis at 00:00 UTC on 09 January (above) demonstrated some important advantages of the 1-km resolution MODIS satellite imagery for the analysis of small-scale water temperature details. The two... Read More
