Another Pioneer Fire pyroCb in Idaho

The Pioneer Fire in central Idaho produced another pyroCb cloud on 29 August 2016. GOES-15 (GOES-West) Visible (0.63 µm), Shortwave Infrared (3.9 µm) and Infrared Window (10.7 µm) images (above; also available as an MP4 animation) showed the development of the pyroCb, which exhibited a minimum cloud-top IR brightness temperature value of -56º C (darker […]

A second pyroCb in Idaho

The Pioneer Fire in central Idaho produced another pyroCb cloud on 21 August 2016 (the first was on 19 August). GOES-14 was in SRSO-R mode, and sampled the fire with 1-minute imagery (above; also available as a large 73 Mbyte animated GIF) — a large smoke plume was evident on 0.63 µm Visible images as […]

PyroCb in Wyoming

A pyroCb cloud developed from the Maple Fire in far northwestern Wyoming during the late afternoon hours on 15 August 2016; GOES-15 (GOES-West) 0.63 µm Visible, 3.9 µm Shortwave Infrared and 10.7 µm Infrared Window images (above; also available as an MP4) showed the fire hot spot (red pixels on the 3.9 µm images) and […]

Fort McMurray, Alberta wildfire

GOES-15 (GOES-West) Visible (0.63 µm) and Shortwave Infrared (3.9 µm) images (above) showed the hot spot (dark black to yellow to red pixels) and the development of pulses of pyrocumulonimbus (pyroCb) clouds associated with a large wildfire located just to the west of Fort McMurray, Alberta (station identifier CYMM) on 03 May 2016. The fire […]

PyroCb near Perth in Western Australia

A 2-panel comparison of Himawari-8 Shortwave Infrared (3.9 µm) and Visible (0.64 µm) images (above) showed the “hot spot” (red pixels) associated with a large bush fire burning near Waroona (south of Perth) in Western Australia on 06 January 2016 (media report), along with smoke from the fire and the explosive development of a pyroCb […]
