1-minute Mesoscale Domain Sector GOES-16 (GOES-East) “Red” Visible (0.64 µm), Shortwave Infrared (3.9 µm) and “Clean” Infrared Window (10.35 µm) images (above) showed the passage of a total solar eclipse shadow across parts of Chile and Argentina, along with the land surface thermal response due to the interruption of incoming solar radiation. In areas... Read More

A toggle between NOAA-20 VIIRS True Color and False Color Red-Green-Blue (RGB) images (above) showed a patch of snow cover that remained across parts of northwestern Oklahoma, the Oklahoma Panhandle and southwestern Kansas on 08 December 2020. This was residual snow cover from a winter storm that occurred 6 days earlier (on... Read More

GOES-17 (GOES-West) Low-level (7.3 µm), Mid-level (6.9 µm) and Upper-level (6.2 µm) Water Vapor images (above) revealed cold thermal signatures (brighter shades of white) associated with the highest-elevation portions of the Alaska Range on 05 December 2020. Note the slight northward shift (16-20 km, or 10-12 miles) in the apparent location of Denali... Read More
