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 Cloud Top Temperature derived product images (above) showed that the Calf Canyon Fire/Hermits Peak Fire in northeastern New Mexico produced a pair of pyrocumulonimbus (pyroCb) clouds on 14 June 2022. Extreme fire behavior was aided by surface wind gusts as high as 60 mph and very... Read More

A sequence of Suomi-NPP VIIRS Visible (0.64 µm), Shortwave Infrared (3.74 µm) and Infrared Window (11.45 µm) images at 2149 UTC and 2332 UTC (above) showed “before” and “after” views of a  pyrocumulonimbus (pyroCb) cloud that developed south of McGrath, Alaska late in the day on 11 June 2022. The... Read More

Preliminary / non-operational GOES-18 “Red” Visible (0.64 µm), Shortwave Infrared (3.9 µm) and “Clean” Infrared Window (10.35 µm) images (above) showed that the Calf Canyon Fire/Hermits Peak Fire in northern New Mexico produced another another pyrocumulonimbus (pyroCb) cloud on 14 May 2022 — following 2 previous pyroCb events on 10 May and 01 May. This particular pyroCb first exhibited cloud-top infrared brightness... Read More

A 3-panel comparison of 1-minute Mesoscale Domain Sector Shortwave Infrared (3.9 µm) images from GOES-17 (GOES-West), GOES-18 (*preliminary, non-operational*) and GOES-16 (GOES-East) (above) showed the hot thermal anomaly (darker black to red pixels) of the Calf Canyon Fire/Hermits Peak Fire in northern New Mexico on 11 May 2022. The images are displayed in the native projection... Read More
