PyroCb in Russia

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 […]
