The Day/Night Band (DNB) utilizes a sun/moon reflectance model that illuminates atmospheric features, and senses emitted and reflected light sources during the nighttime hours. The DNB is at 0.7um and is apart of 22 spectral channels on-board the Suomi National Polar-orbiting Partnership (S-NPP) satellite and the new NOAA-20 satellite. In the DNB video below (using Continue Reading

It is that time of year again, to observe Santa Ana Wind events for Southern California. On 15 October 2018, an upper-level trough advected into the southwestern United States (i.e. see GOES-16, Upper Level Water Vapor imagery below), produced cold air advection aloft, and brought strong subsidence (i.e. sinking motion) to the surface. The strong Continue Reading
Hurricane Michael has made landfall today, along the Florida Panhandle, between Tyndall Air Force Base, FL and Mexico Beach, Florida. Radar and satellite products observed Michael, as it approached the Florida Panhandle (seen below).

By Louie Grasso, Dan Bikos, Jorel Torres and Ed Szoke During the summer of 2018 over the High Plains, several significant severe storms occurred. Several hailstorms moved southward over the Central High Plains and produced noticeable hail swaths and damage scars on the ground that were captured by GOES-16 ABI. The purpose of this blog Continue Reading
