On 22 June 2017 a pyroCb formed from the Brian Head Fire in Utah. GOES-15 detected the smoke plumes and pyroCb cloud, as well as the fire hot spot. The pyroCb cloud (~37.7º N, 112.8ºW) formed around 23:30 UTC . Starting at 23:00 UTC on 21 June, the animation below shows GOES-15 0.63 µm visible (left) and […]
On 19 June 2017 a pyroCb formed in Yukon. GOES-15 detected the smoke plumes and pyroCb cloud, as well as the fires hot spot. The pyroCb cloud (~66º N, 137ºW) formed around 23:30 UTC . Starting at 22:00 UTC on 19 June, the animation below shows GOES-15 0.63 µm visible (left) and 3.9 µm shortwave IR (right) […]
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 […]
Himawari-8 Visible (0.64 µm), Shortwave Infrared (3.9 µm) and Longwave Infrared Window (10.4 µm) images (above) showed a wildfire burning in Russia on 25 May 2017 at 58.3N 106.2E. This fire reached a minimum brightness temperature around -40ºC around 8:30 UTC. Suomi NPP OMPS Aerosol Index images (courtesy of Colin Seftor) shows the transport of smoke on […]
A slightly longer animation — covering the period from 20:40 on 6 December to 09:40 UTC on 7 December — of Himawari-8 Visible (0.64 μm), Shortwave Infrared (3.9 μm) and Infrared Window (10.4 μm) images is shown below. The pyroCb cloud formed near the center of the images, and the cold anvil of the cloud […]
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, […]
