1-minute Mesoscale Domain Sector GOES-17 (GOES-West) “Red” Visible (0.64 µm), Fire Temperature RGB, “Clean” Infrared Window (10.35 µm) and Cloud Top Temperature derived product images (above) showed that the rapidly-growing McKinney Fire in far northern California produced multiple (5 or 6) pulses of pyrocumulonimbus (pyroCb) clouds late in the day on 30 July 2022. The coldest pyroCb cloud-top 10.35... Read More
GOES-18 images shown in this blog post are preliminary and non-operational During its Post-Launch Testing (PLT) period, once GOES-18 drifted to a position close to its final “Operational GOES-West” longitude of 137º W, a “Barcode Artifact” of vertical striping was occasionally seen in colder scenes of Band 07 Shortwave Infrared (3.9 µm)...

GOES-16 (GOES-East) “Clean” Infrared Window (10.35 µm) images (above) showed the development of multiple clusters of thunderstorms that were responsible for producing heavy rainfall and flash flooding across parts of eastern Kentucky during the nighttime hours leading up to sunrise on 28 July 2022. The coldest GOES-16 cloud-top infrared brightness temperature associated with these thunderstorms was -82.7ºC... Read More
GOES-16 (GOES-East) “Clean” Infrared Window (10.35 µm) images (above) showed the development of an elongated band of training thunderstorms that was responsible for producing record rainfall and flash flooding in the St. Louis, Missouri area during the nighttime hours leading up to sunrise on 26 July 2022. The coldest GOES-16 cloud-top infrared brightness temperatures... Read More
