1-minute Mesoscale Domain Sector GOES-18 (GOES-West) Day Land Cloud Fire RGB, Shortwave Infrared (3.9 µm), “Clean” Infrared Window (10.3 µm) and Cloud Top Temperature derived product images (above) showed that the Spoon Fire in in east-central Arizona produced a pyrocumulonimbus (pyroCb) cloud late in the day on 27 July 2023. Cloud-top 10.3 µm brightness temperatures reached the -40ºC pyroCb threshold (shades of blue) at 0043 UTC... Read More

GOES-18 (GOES-West) Day Land Cloud Fire RGB, Shortwave Infrared (3.9 µm), “Clean” Infrared Window (10.3 µm) and Visible images with an overlay of the Fire Power derived product — Fire Power is a component of the GOES Fire Detection and Characterization Algorithm FDCA — (above) showed thermal signatures associated with a wildfire that produced a pair of pyrocumulonimbus (pyroCb)...

GOES-16 (GOES-East) Day Land Cloud Fire RGB, Shortwave Infrared (3.9 µm), “Red” Visible (0.64 µm) with an overlay of the Fire Temperature derived product and Visible images with an overlay of the Fire Power derived product — both derived products being components of the GOES Fire Detection and Characterization Algorithm FDCA — (above) showed thermal signatures associated...

GOES-18 (GOES-West) Day Land Cloud Fire RGB, Shortwave Infrared (3.9 µm), “Clean” Infrared Window (10.3 µm) and Near-Infrared “Vegetation” (0.86 µm) images with an overlay of the Fire Power derived product (a component of the GOES Fire Detection and Characterization Algorithm FDCA) (above) showed that the Hossitl Creek wildfire complex northeast of Fort Nelson (CYYE) — in far northeastern British Columbia...
