On the current operational GOES-11 and GOES-12 satellites, data losses occur for several hours each day during the weeks centered around the Spring and Autumn equinox due to (1) Keep-Out Zones (KOZ), and (2) Eclipse. During KOZ, sunlight impinging upon the optical path of the instrument detectors requires the GOES... Read More
A large mesoscale convective system (MCS) developed over Nebraska during the pre-dawn hours on 24 June 2008, and AWIPS images of the GOES-12 10.7 µm IR channel (above) showed the extensive coverage of very cold cloud top temperatures (-60 to -70º C, red to black color enhancement) associated with this convective activity....

AWIPS images of the MODIS visible channel along with the Normalized Difference Vegetation Index (NDVI) and Land Surface Temperature (LST) products (above) depicted the areal extent of the Mississippi Alluvial Valley (MAV) on 12 May 2008. This physiographic feature represents the historical flood plain of the lower Mississippi River, which stretches from... Read More
