Ferguson Fire pyroCb in California

* GOES-17 images shown here are preliminary and non-operational * The Ferguson Fire in central California produced a pyrocumulonimbus (pyroCb) cloud during the afternoon hours on 15 July 2018. GOES-16 (GOES-East) “Red” Visible (0.64 µm), Shortwave Infrared (3.9 µm) and “Clean” Infrared Window (10.3 µm) images (above) showed that the high-altitude portion of the pyroCb […]

PyroCb in Colorado

GOES-16 (GOES-East) “Red” Visible (0.64 µm), Shortwave Infrared (3.9 µm) and “Clean” Infrared Window (10.3 µm) images (above) showed the formation of a small pyroCb cloud spawned by the 416 Fire in southwestern Colorado on 09 June 2018. A Mesoscale Domain Sector was positioned over the region, providing images at 1-minute intervals. On Shortwave Infrared […]

PyroCb in Ontario, Canada

GOES-16 “Red” Visible (0.64 µm), Shortwave Infrared (3.9 µm) and “Clean” Infrared Window (10.3 µm) images (above) showed that Canadian wildfires burning along the Manitoba/Ontario border produced a pyroCb around 1930 UTC on 22 May 2018. As the pyroCb moved southeastward over western Ontario, the coldest GOES-16 cloud-top infrared brightness temperatures were around -55ºC (orange […]

PyroCb in British Columbia

On 12 September 2017 a pyroCb formed in British Columbia. GOES-15 detected the smoke plumes and pyroCb cloud, as well as the fires hot spot. The pyroCb cloud (~50.4º N, 110.3ºW) formed around 0:00 UTC . Starting at 22:00 UTC on 11 September, the animation below shows GOES-15 0.63 µm visible (left) and 3.9 µm shortwave IR […]

PyroCb in Washington State

On 05 September 2017 a pyroCb formed in Washington. GOES-15 detected the smoke plumes and pyroCb cloud, as well as the fires hot spot. The pyroCb cloud from the Jolly Mountain Fire (~47.4º N, 121.0ºW) formed around 1:00 UTC . Starting at 0:00 UTC on 05 September, the animation below shows GOES-15 0.63 µm visible (left) and […]

PyroCb in Oregon

On 04 September 2017 a pyroCb formed in Oregon. GOES-15 detected the smoke plumes and pyroCb cloud, as well as the fires hot spot. The pyroCb cloud (~45.7º N, 121.9ºW) formed around 23:00 UTC . Starting at 22:00 UTC on 04 September, the animation below shows GOES-15 0.63 µm visible (left) and 3.9 µm shortwave IR (right) […]
