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.... Read More

1-minute Mesoscale Domain Sector GOES-17 (GOES-West) Night Fog brightness temperature difference (BTD) and “Red” Visible (0.64 µm) images (above) showed the nighttime and daytime signature of a fog/stratus layer that had persisted throughout much of the Snake River Basin in southern Idaho on 29 December 2020. Some sites along the Interstate 84 corridor were reporting... Read More

CIMSS is now producing IFR Probability fields (and Low IFR Probability, Marginal VFR Probability, and Cloud Thickness fields) using GOES-17 data.  (Recall that GOES-16 IFR Probability fields  are now produced by NOAA/NESDIS and are distributed via the Satellite Broadcast Network (SBN) to National Weather Service Forecast Offices.  GOES-16, however, does...

When GOES-15 stopped sending data, IFR Probability fields based on GOES-15 ceased being sent over LDM to users. CIMSS is now sending GOES-17 IFR Probability fields (shown in a toggle above with the Night Fog Brightness Temperature Difference field) via the EXP LDM feed from CIMSS.  Particular strengths of IFR Probability fields include giving a useful low cloud signal below...
