Overlapping 1-minute GOES-16 (GOES-East) Mesoscale Domain Sectors provided 30-second “Red” Visible (0.64 µm) images (above), which included time-matched plots of SPC Storm Reports — showing clusters of thunderstorms that moved eastward across parts of Illinois, Indiana and Lower Michigan on 03 August 2022.The corresponding 30-second GOES-16 “Clean” Infrared Window (10.35 µm) images (below) indicated that the coldest...

Beginning at 1713 UTC on 01 August 2022, GOES-18 began serving as GOES-West during an operational interleave period — so GOES-18 imagery routinely became available in AWIPS. Examples of GOES-18 “Red” Visible (0.64 µm) and Mid-level Water Vapor (6.9 µm) images from a combination of the Alaska, Pacific-US (PACUS) and Hawai`i Sectors are... Read More

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)...
