(Click image for larger version)GOES-15 is observing from a vantage point above the Equator at 89.5 W and GOES-13 is observing from a vantage point above the Equator at 75 W. The two satellites therefore have slightly different perspectives of cloud scenes over the southeast United States. These different perspectives... Read More

The image loop above shows GOES-15 11-micron imagery every half hour as Tropical Depression #4 in the Atlantic strengthened to become a minimal Tropical Storm, gaining the name Colin in the process. The infrared imagery shows periodic bursts of convection with brightness temperatures colder than -70 C near the center... Read More

Severe thunderstorms propagated southeastward across far northeastern Montana late in the day on 26 July 2010. McIDAS images of GOES-11 (GOES-West), GOES-15, and GOES-13 (GOES-East) 10.7 µm IR data (above; each image set is displayed in the naive projection of the respective satellite) showed that a subtle “enhanced-v” storm top signature first...
