The GOES-14 satellite was brought out of storage on 11 August 2021, for its annual checkout activities (NOAA bulletin). Shortwave Infrared (3.9 µm) images (above) provided a 4-GOES view of the thermal anomalies (or hot pixels, darker black enhancement) exhibited by the Richard Spring Fire in southeastern Montana. On that day the fire had burned... Read More

5-minute GOES-17 (GOES-West) “Red” Visible (0.64 µm), Shortwave Infrared (3.9 µm), “Clean” Infrared Window (10.35 µm) and Fire Temperature RGB images (above) revealed that the Dixie Fire in northern California produced a pair of pyrocumulonimbus (pyroCb) clouds — denoted by cloud-top 10.35 µm infrared brightness temperatures of -40ºC or colder (shades of blue pixels) — late in the day on 19 July 2021....

1-minute Mesoscale Domain Sector GOES-17 (GOES-West) “Red” Visible (0.64 µm), Shortwave Infrared (3.9 µm), “Clean” Infrared Window (10.35 µm) and Fire Temperature RGB images (above) revealed that the Bootleg Fire in far southern Oregon produced a pyrocumulonimbus (pyroCb) cloud — denoted by cloud-top 10.35 µm infrared brightness temperatures of -40ºC and colder (darker blue pixels) — late in the day...

GOES-17 (GOES-West) “Red” Visible (0.64 µm), Shortwave Infrared (3.9 µm) and “Clean” Infrared Window (10.35 µm) images (above) showed the explosive formation of large pyrocumulonimbus (pyroCb) clouds that were spawned by large wildfires in British Columbia, Canada on 30 June 2021. The 10.35 µm cloud-top infrared brightness temperatures rapidly cooled to the -50 to -60ºC range,... Read More
