One of the products demonstrated at the Hazardous Weather Testbed (HWT) in Norman in May and June this year was GREMLIN (GOES Radar Estimation via Machine Learning to Inform NWP) a tool created with Machine Learning (by Kyle Hilburn at CIRA) to use ABI and GLM data to create synthetic... Read More

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...

GOES-18 imagery over California at 1836 UTC (above, left) show a very strong signal over San Luis Obispo County: very bright in visible imagery and warm in the shortwave infrared. In the GOES-16 imagery, that signal is not present. In contrast, the warm signal in the shortwave infrared in GOES-18... Read More
