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, […]

PyroCb in Cecil Plains

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 […]

Another PyroCb in Idaho

On 24 August a pyroCb formed  from the Henry Creek Fire in Idaho. GOES-15 detected the smoke plumes and pyroCb cloud, as well as the fire hot spot. The pyroCb (43.4º N, 111.7º W) formed around 23:45 UTC .  Starting at 23:00 UTC on 24 August, the animation below (also available as an MP4) )shows GOES-15 (GOES-West) 0.63 µm […]

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 Idaho

A small pyroCb cloud developed from the Pioneer Fire in Idaho during the evening hours on 19 August 2016, which difted quickly to the southwest; GOES-15 (GOES-West) 0.63 µm Visible and 3.9 µm Shortwave Infrared images (below) showed the fire hot spot (red pixels on the 3.9 µm images) and the pyroCb plume in the visible. Since the pyroCb occurred […]
