A comparison of 375-meter resolution Suomi NPP VIIRS 0.64 µm visible, 3.74 µm shortwave IR, and 11.45 µm IR images at 2125 UTC on 30 May 2015 (above) showed widespread smoke plumes and “hot spots” (yellow to red to black enhancement) from wildfires that were burning across far western portions of Canada’s Northwest Territories and […]
The first verified pyrocumulonimbus (pyroCb) cloud of the 2015 wildfire season formed in central British Columbia, Canada late in the day on 12 May 2015. A comparison of GOES-15 (GOES-West) 0.63 µm visible and 3.9 µm shortwave IR images (above; click image to play animation; also available as an MP4 movie file) showed the growth […]
The South Fork fire complex had been burning since being started by lightning on 31 July 2014 (InciWeb), and a pyroCb was seen to develop late in the day on 09 August 2014. A 4-panel comparison of GOES-15 (GOES-West) and GOES-13 (GOES-East) 0.63 µm visible channel and 3.9 µm shortwave IR channel images (above; click […]
On the evening of 29 July 2014, a small pyroCb cloud was produced by a one of the ongoing fires in the Northwest Territories of Canada. GOES-15 0.63 µm visible channel and 3.9 µm shortwave IR channel images (above; click image to play animation; also available as an MP4 movie file) showed that the pyroCb […]
åAfter several days of wildfire activity over parts of northern British Columbia (BC), northern Alberta (AB), and the Northwest Territories (NWT) of Canada (which produced a great deal of smoke, but no pyroCb activity), the conditions of the synoptic-scale environment became more favorable on 14 July 2014, allowing multiple pyroCb events (at least five?) to […]
Kudos to Mark Ruminski (NOAA/NESDIS Satellite Analysis Branch) for spotting this pyroCB event in far northern Alberta, Canada late in the day on 14 June 2014.
