The storm system that struck the Tennessee Valley on 10 April 2009 presented several impressive satellite images. The image shown above is an overlay of 1 km MODIS visible imagery with 1 km MODIS 11 micron infrared imagery (in color). The image combination tool in AWIPS allows for a unique presentation as the visible imagery shows cloud structure, especially with some of the towering cumulonimbus clouds and cirrus shield assoctiated with the severe weather. The infrared imagery shows the coldest cloud tops associated with the strongest storms, shown by the pink region. The image below demonstrates the full power of MODIS. This visible image has a resolution of 250 m and is a snapshot of the powerful thunderstorms that would later impact the central and eastern portions of the Tennessee Valley. Unlike the more well known GOES imagery, MODIS can only provide a snapshot image as it is aboard a polar orbiting satellite. However, MODIS gives us a preview of future capabilities.
