PyroCb in South Africa

The Garden Route Fires had been burning since about 24 October 2018 near George along the southern coast of South Africa (media story). On 29 October, EUMETSAT Meteosat-11 High Resolution Visible (0.8 µm), Shortwave Infrared (3.92 µm) and Longwave Infrared Window (10.8 µm) images (above) showed an elongated west-to-east oriented thermal anomaly or fire “hot […]

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 […]
