1-minute Mesoscale Domain Sector GOES-18 (GOES-West) Day Fire RGB, Shortwave Infrared (3.9 µm), and “Red” Visible (0.64 µm) images with overlays of the Fire Power and Fire Mask derived product (2 components of the GOES Fire Detection and Characterization Algorithm FDCA) (above) displayed signatures of the Post Fire, which reportedly started around 2052 UTC on 15 June 2024 near Gorman, California (in far northwest...

Thousands if not millions of people took colorful photos of the Northern Lights during the early hours of May 11th during a remarkable G5 geomagnetic storm that expanded Aurora Borealis activity southward to unusually low latitudes in the United States. The JPSS fleet of polar-orbiting spacecraft captured eight monochromatic VIIRS... Read More
The long-anticipated arrival of NOAA-21 NUCAPS profiles (to supplement NOAA-20!) to AWIPS means that data void regions such as the South Pacific Ocean now have complete twice-daily coverage, as shown by the inidividual profiles above, and the overlapping profiles below. This means that a twice-daily mappings of accurate satellite sounder-provided... Read More
NUCAPS profiles from NOAA-21 are now flowing into AWIPS, joining NUCAPS from NOAA-20 and Metop-C. NOAA-21 and NOAA-20 orbits are similar, and the combination of the two satellites means complete coverage twice daily. That is demonstrated in the animation above over Hawai’i that shows gridded NUCAPS fields of 500-mb temperatures... Read More
