On 01 June a pyroCb formed in Russia (56.5 N, 103.8E). HIMAWARI-8 detected the smoke plume and pyroCb cloud, as well as the fire hot spot. Starting at 5:00 UTC on 01 June, the animation below shows visible (.63 μm) on the left and shortwave IR (3.9 μm) on the right (click image to play animation). In the shortwave IR images the red pixels indicate very hot IR brightness temperatures exhibited by the fire source region.

In addition, using HIMAWARI-8 10.4 μm IR channel the cloud-top IR brightness temperature could be found. The animation below, starting at 6:30 UTC on 01 June, shows the brightness temperature for the pyroCb is -46.4ºC around 07:10 UTC (lime green color enhancement).

OMPS AI index images (courtesy of Colin Seftor) shows the transport of smoke on 2 June. The maximum AI index was found to be 3.7 at 54.8 N 115.4 E around 5:50 UTC. This is east of the original pyroCb indicating an eastward movement of the smoke.
