10-minute Full Disk scan GOES-18 (GOES-West) daytime True Color RGB and Nighttime Microphysics RGB images — created using Geo2Grid (above) — showed the offshore transport of glacial silt from the Copper River Delta in Southcentral Alaska from 11-23 December 2025. Even though cloud cover occasionally obscured the signature of this plume of airborne... 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) Visible images (above) showed a rapidly intensifying Hurricane Force Low (surface analyses) that was approaching Atlantic Canada on 04 November 2025.Two examples of Metop ASCAT surface scatterometer winds having speed values greater than Category 1 hurricane intensity are shown below. 5-minute GOES-19 Water Vapor images (below) depicted a mid-tropospheric...
