As the Rim Fire continues to burn near Yosemite National Park in California on August 21st, 2013, another pyrocumulonimbus has spawned from the complex. Looking at the GOES-15 visible imagery (above, left; click image to play animation), a large plume of cloud can be seen erupting from the fire, centered approximately at 38N 120W, at about 22 UTC.

A PyroCB event occurred in Montana on August 19, 2013, as seen with GOES-14 imagery. A two-panel comparison (above; click image to play animation) shows the visible imagery (top panel) as well as the shortwave infrared imagery (bottom panel). Hot spots are already apparent in Wyoming, and around 20:45 UTC, a hot spot flares up […]
…Note: scroll down to the bottom of this post for 22 August and 23 August updates… On August 19, 2013, the Rim Fire complex in Groveland, CA spawned a pyrocumulonimbus cloud as it burned through the Stanislaus National Forest. The GOES-14 satellite was also placed into Super Rapid Scan Operations for GOES-R (SRSO-R) for the day, […]
Mike Fromm (NRL) coined the term “pyrobubbles”, and pointed out 3 examples that occured on 16 August 2013. We shall examine each of thse 3 cases using GOES-15 (GOES-West) imagery. The first pyrobubble originaled from a fire near the Idaho/Montana border; GOES-15 0.63 µm visible channel images (above; click image to play animation) showed the […]
Sparked on Saturday, August 11, the Tooele County wildfire continued to burn through Wednesday, August 14, belching a large amount of smoke into the atmosphere. GOES-15 visible imagery (above, left panel; click image to play) depicts a fair amount of smoke being ejected from the fire and a small pyrocumulonimbus cloud forming rapidly near the end of the […]
The GOES-14 satellite was placed into Super Rapid Scan Operations for GOES-R (SRSO-R) mode on 13 August 2013, providing imagery at 1-minute intervals. The development of a well-defined pyrocumulonimbus (pyroCb) cloud produced by a large fire burning to the east of Boise in southern Idaho can be seen in a comparison of GOES-14 0.63 µm […]
