GOES-16 versions of the GOES-R Fog/Low Stratus products, such as IFR/Low IFR/Marginal VFR Probability fields, and GOES-R Cloud Thickness, are now available in RealEarth. These products are still available at the CIMSS GEOCAT site as well (link, for an image like this), but RealEarth offers pan, zoom and overlay capabilities. The RealEarth image from 1401 UTC on 5 January is shown above; the same time image from AWIPS is shown below. This link shows a more recent image in RealEarth.
