VIIRS Infrared images from Suomi-NPP and NOAA-21 (above) showed widespread ice leads in the Chukchi Sea during the 3-day period from 06-08 January 2026. A combination of surface wind stress and ocean currents influenced the motion and evolution of these ice leads.Surface analyses (below) showed a tighter pressure gradient across the... Read More
A somewhat unusual feature was visible off of the coast of Wisconsin’s Door Peninsula on 15 December 2025. Bands of clouds were separated by narrow, tight corridors of clear air. Such straight lines are not common for natural features in the atmosphere, which hints that they may be anthropogenic in... Read More
10-minute Full Disk scan GOES-18 (GOES-West) daytime True Color RGB and nighttime Dust RGB images created by Geo2Grid (above) highlighted plumes of glacial silt being transported offshore by strong katabatic winds that were occurring in the northern Alaska panhandle on 09-10 December 2025. Note the strong pressure gradient between a ridge of... Read More
5-minute CONUS Sector GOES-19 (GOES-East) Nighttime Microphysics RGB + daytime True Color RGB images from the CSPP GeoSphere site (above) showed numerous power plant plumes (shades of red) embedded within a supercooled water droplet c loud layer (shades of yellow) that covered much of Wisconsin on 02 December 2025.The GOES-19 Cloud Top Phase derived product (below) confirmed...
