A Landsat-8 False Color Red-Green-Blue (RGB) image as viewed using RealEarth (above) showed areas of flooding (water = darker shades of blue) along portions of the Innoko River and the Iditarod River in Southwest Alaska on 05 May 2020. Much of southwestern Alaska had received above-average winter season snowfall —... Read More

GOES-16 (GOES-East) “Red” Visible (0.64 µm) images (above) showed widespread boundary layer wave clouds across much of Kansas and far eastern Colorado on 02 May 2020. Although there was a temporary outage of pilot report data from 18-19 UTC, there was one pilot report of light turbulence over Hays, Kansas (KHYS) at an... Read More
