PyroCb in Utah

On 22 June 2017 a pyroCb formed in Utah. GOES-15 detected the smoke plumes and pyroCb cloud, as well as the fires hot spot. The pyroCb cloud (~37.7º N, 112.8ºW) formed around 23:30 UTC . Starting at 23:00 UTC on 22 June, the animation below shows GOES-15 0.63 µm visible (left) and 3.9 µm shortwave IR (right) […]

Two PyroCbs in Russia

On 22 June 2017 two pyroCbs formed north of Lake Baikal in eastern Russia. Himawari-8 detected the smoke plume and pyroCb cloud, as well as the fires hot spots. The first pyroCb cloud (~58.3º N, 105ºE) formed around 8:30 UTC . The second formed shortly after around 58.9º N  106.9ºE. Starting at 8:00 UTC on 22 June, […]

Two PyroCbs in Russia

On 12 June 2017 two pyroCbs formed northwest of Lake Baikal in eastern Russia. Himawari-8 detected these smoke plumes and pyroCbs cloud, as well as the fires hot spots. The first pyroCb cloud (~54.3º N, 105.7ºE) formed around 9:20 UTC . The second pyroCb cloud (~55.4º N, 107.4ºE) formed around 10:50 UTC. Starting at 9:00 UTC on […]

Another PyroCb in Cecil Plains

Another pyroCb formed on 06 December in Cecil Plains in Queensland, Australia. Starting at 4:00 UTC on 06 December, the animation below (also available as an MP4) shows Himawari-8 0.63 µm visible (left) and 3.9 µm shortwave IR (right) . The pyroCb cloud (~28.2º S, 151ºE) formed around 7:50 UTC. In the shortwave IR images, […]

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 […]
