GOES-18 (GOES-West) SO2 RGB and Ash RGB images (above) showed the complex transport of a volcanic cloud produced by an explosive eruption of Mount Shishaldin that began around 1350 UTC on 03 October 2023. The bulk of the higher-altitude volcanic cloud was rich in SO2 (shades of yellow in both RGB types), while a smaller mid-level portion that had... Read More
10-minute GOES-18 (GOES-West) “Red” Visible (0.64 µm) + Fire Power derived product (a component of the GOES Fire Detection and Characterization Algorithm FDCA), Shortwave Infrared (3.9 µm), “Clean” Infrared Window (10.3 µm) and Day Land Cloud Fire RGB images (above) showed a wildfire east of Fort Nelson (CYYE) in far northeastern British Columbia that produced 3 consecutive pyrocumulonimbus (pyroCb) cloud pulses late...
