PyroCbs in Montana

On 03 September 2017 two pyroCbs formed in the Montana. GOES-15 detected the smoke plume and pyroCb cloud, as well as the fires hot spots. The first pyroCb cloud (~45.3º N, 115.1ºW) formed around 23:00 UTC on 03 September . The second formed shortly after around 45.8º N  114.9ºE at 23:30 UTC on 03 September. […]

PyroCbs in Oregon

On 29 August 2017 two pyroCbs formed in the Oregon. GOES-15 detected the smoke plume and pyroCb cloud, as well as the fires hot spots. The first pyroCb cloud (~44º N, 121.1ºW) formed around 20:15 UTC on 29 August . The second formed shortly after around 43.8º N  121.4ºE at 0:00 UTC on 30 August. […]

PyroCb in Alaska

On 09 July 2017 a pyroCb formed in Alaska. GOES-15 detected the smoke plumes and pyroCb cloud, as well as the fires hot spot. The pyroCb cloud (~67.5º N, 141.4ºW) formed around 3:00 UTC . Starting at 2:30 UTC on 09 July, the animation below shows GOES-15 0.63 µm visible (left) and 3.9 µm shortwave IR (right) […]

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 […]
