GOES-16 (GOES-East) Visible images (above) showed the hazy signature of a narrow plume of blowing dust that developed across West Texas on 30 December 2024. Lofted by strong NW winds behind a dryline, this blowing dust briefly reduced the surface visibility to 3.5 miles at Big Spring (KBPG) and 7... Read More
5-minute CONUS Sector GOES-19 (Preliminary/Non-operational) True Color RGB and Blowing Snow RGB images created using Geo2Grid (above) displayed a small patch of radiation fog over Lake Mendota that slowly dissipated during the morning hours on 25th December 2024 (the Blowing Snow RGB is a modified version of the Day Snow-Fog RGB, which uses higher spatial resolution Band 2...

10-minute JMA Himawari-9 AHI “Red” Visible (0.64 µm), Shortwave Infrared (3.9 µm) and “Clean” Infrared Window (10.4 µm) images (above) showed the formation of a pyrocumulonimbus (pyroCb) cloud that was spawned by a bushfire in Grampians National Park in far southeast Australia on 20th December 2024. The pyroCb cloud exhibited cloud-top 10.4... Read More
