1-minute Mesoscale Domain Sector GOES-18 (GOES-West) Fire Temperature RGB and “Clean” Infrared Window (10.3 µm) images (above) showed the intensification of 3 wildfires in northeast British Columbia on 20 May 2023. Two of the fires produced pyrocumulonimbus (pyroCb) clouds, exhibiting cloud-top 10.3 µm infrared brightness temperatures of -50ºC or colder (shades of red) — which then eventually moved eastward...

True-Color imagery from GOES-East (above, from the CSPP Geosphere site) and GOES-West (below, also from the CSPP Geosphere site) from 1720-1910 UTC show multiple active fires in British Columbia, Alberta and Manitoba, and a wide plume of smoke entrained into a storm centered just north of Saskatchewan (one wonders if the rain from the storm...

10-minute Full Disk sector GOES-18 (GOES-West) Fire Temperature RGB, “Clean” Infrared Window (10.3 µm), Cloud Top Height and Cloud Top Temperature (above) showed the formation of a pyrocumulonimbus (pyroCb) cloud produced by a wildfire southeast of Edson, Alberta (station identifier CYET) on 04 May 2023. Cloud-top 10.3 µm infrared brightness temperatures were as cold as -61ºC, while the multispectral... Read More

5-minute CONUS sector GOES-16 (GOES-East) True Color RGB images from the CSPP GeoSphere site (above) showed the northward transport of smoke from the 35,000-acre Great Lake Fire in eastern North Carolina on 21 April 2023.In a closer view using 1-minute Mesoscale Domain Sector GOES-16 True Color RGB images (below), intermittent brighter white pyrocumulus clouds were...
