1-minute Mesoscale Domain Sector GOES-16 (GOES-East) “Red” Visible (0.64 µm), GOES-17 Shortwave Infrared (3.9 µm), Fire Temperature Red-Green-Blue (RGB) + GLM Flash Extent Density (FED) and “Clean” Infrared Window (10.35 µm) images (above) showed 2 distinct pulses of pyrocumulonimbus (pyroCb) cloud emanating from the Cameron Peak Fire in north-central Colorado on 06 September 2020. The coldest cloud-top infrared brightness temperatures were -52.4ºC. Smoke was occasionally restricting the... Read More

1-minute Mesoscale Domain Sector GOES-17 (GOES-West) “Red” Visible (0.64 µm), GOES-17 Shortwave Infrared (3.9 µm), Fire Temperature Red-Green-Blue (RGB) + GLM Flash Extent Density (FED) and “Clean” Infrared Window (10.35 µm) images (above) showed the formation of a pyrocumulonimbus (pyroCb) cloud created by the Creek Fire in Central California on 05 September 2020. The appearance of a few brief GLM FED pixels (2026 UTC | 2117 UTC)... Read More

1-minute Mesoscale Domain Sector GOES-17 (GOES-West) “Red” Visible (0.64 µm) and Shortwave Infrared (3.9 µm) images (above) showed the dense smoke plume and thermal anomalies (clusters of yellow to red to black pixels) associated with the SQF Complex of wildfires that had been burning since 24 August. Also evident in the Visible imagery was the presence of brighter white pyrocumulus... Read More

1-minute Mesoscale Domain Sector GOES-17 (GOES-West) Shortwave Infrared (3.9 µm) images (above) showed a number of thermal anomalies — clusters of hot pixels, yellow to red enhancement — associated with wildfires that developed across parts of Montana on 02 September 2020. The SPC Fire Weather Outlook had highlighted critical to extreme fire weather conditions over much of that region,... Read More
