A well-defined “enhanced-v” storm top signature was seen on MODIS 11.0 µm IR window image (above) over Nebraska around 08:09 UTC (3:09 am local time) on 13 May 2009. The magnitude of the cold/warm cloud top temperature couplet was rather large (-72º... Read More
AWIPS images of the 1-km resolution MODIS fog/stratus product and the 4-km resolution GOES-12 fog/stratus product (above) demonstrate the advantage of higher spatial resolution for the detection of widespread small-scale fingers of valley fog that had formed during the overnight hours over much of the southern Appalachian Mountains states on...

An unusually-large derecho event formed over Kansas during the pre-dawn hours on 08 May 2009, and then moved rapidly eastward across Missouri and Illinois during the morning hours. GOES-12 10.7 µm IR window images (above) showed the large areal coverage of cold... Read More
AWIPS images of the 1-km resolution MODIS 6.5 µm and the 4-km resolution GOES-12 6.5 µm “water vapor channel” images (above) demonstrate the advantage of better spatial resolution for the detection of small-scale features such as the mountain waves that had formed over much of New Mexico and the adjacent...
