PyroCb in Australia

On 04 December 2016 a pyroCb developed to the west of Toowoomba in Queensland, Australia. A Suomi NPP VIIRS true-color image around 04:16 UTC (above) showed the early stage of the smoke plume in the Cecil Plains area, about 2 hours prior to the pyroCb formation. Himawari-8 monitored the temporal evolution of the smoke plumes and […]

PyroCb in Russia

On 19 September 2016 a pyroCb formed northwest of Lake Baikal in eastern Russia. Himawari-8 detected the smoke plumes and pyroCb cloud, as well as the fire hot spots. The pyroCb cloud (~57.4º N, 105.3ºE) formed around 8:20 UTC . Starting at 7:30 UTC on 19 September, the animation below (also available as an MP4) shows Himawari-8 […]

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 […]
