The Day-Night Band from VIIRS on the Suomi/NPP has been giving excellent imagery of Tropical Storms Ernesto and Florence over the weekend. The views are especially crisp because of the near fullness of the moon. For example, the sheared nature of Ernesto (top) is evident, and the overshooting tops in... Read More
A comparison of AWIPS images of 1-km resolution MODIS 0.65 µm visible channel data and the corresponding MODIS Land Surface Temperature (LST) product (above) showed nearly cloud-free conditions and very hot LST values of 120 – 140 F (darker red color enhancement) across much of southern Oklahoma at 19:48 UTC...

A strong tropical wave near 50 W Longitude in the central Atlantic has become a Tropical Depression. The enhanced infrared image above shows a region of active convection (as signified by the overshooting tops designated by yellow circles) near the center of the system. (Current imagery of overshooting tops can... Read More
A large mesoscale convective system (MCS) developed in western Tennessee, which then grew in size and intensity as it propagated southward across Alabama on 31 July 2012. An AWIPS image of 1-km resolution POES AVHRR 10.8 µm IR channel data (above) showed cloud top IR brightness temperatures as cold as... Read More
