DNB: Ship Light Monitoring and Sea Ice Motion

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.

Santa Ana Winds and Dust Identification

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
