The visible image, above, from 1830 UTC on 25 August, shows a distinct cloud edge arcing from northwest to southeast. What is the history of this feature? The... Read More
The normal operational GOES scan schedule provides one full disk image every 3 hours — but as part of the GOES-15 NOAA Science Test, the GOES-15 satellite was placed into a mode which allowed one full disk image to be scanned every 30 minutes. McIDAS images of GOES-15 6.5 µm “water vapor channel”... Read More
McIDAS images of GOES-11 0.65 µm visible channel data (above) revealed the southern edge of the ice in the Beaufort Sea (north of Alaska and Canada’s Yukon and Northwest Territories) on 18 August 2010.A closer view using a 1-km resolution NOAA-18 AVHRR false color Red/Green/Blue (RGB) image (below) showed that...

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...
