A comparison of 250-meter resolution MODIS true color<\/strong><\/a> Red\/Green\/Blue (RGB) images from the SSEC MODIS Today<\/strong><\/a> site (above)<\/strong><\/em> shows the breakup of ice in the northern portion of Green Bay, Wisconsin. It can be seen that there is a significant amount of ice motion (due to southwesterly winds)<\/em> in the time between the 16:52 UTC<\/strong> Terra MODIS image and the 18:35 UTC<\/strong> Aqua MODIS image — and other smaller ice floes can also be seen moving in portions of northern Lake Michigan and southern Lake Superior. Also note that the southwest-to-northeast oriented long-track tornado<\/strong><\/a> damage path from the 07 June 2007 severe convection event<\/strong><\/a> could still be clearly identified about 100 km to the west of the ice-covered portion of Green Bay.<\/p>\n

An animation of McIDAS images of 1-km resolution GOES-13 0.63 \u00c2\u00b5m visible channel data (below; click image to play animation)<\/strong><\/em> does show the movement of the ice in the northern portion of Green Bay during the day — but even at an image interval of 15 minutes, errors in the Image Navigation and Registration (INR) tend to produce a bit of “wobble” which makes tracking the ice motion more difficult.<\/p>\n

With the next-generation Advanced Baseline Imager (ABI)<\/strong><\/a> on the future GOES-R<\/strong><\/a> satellite, the spatial resolution of the visible channel will be improved to 500 meters — and the nominal temporal resolution of images over the continental US will be every 5 minutes (although 30-second image intervals will be available for special weather situations)<\/em>.
