GOES-16 (GOES-East) Ash RGB images and Dust RGB images (above) showed numerous volcanic plumes emanating from Popocatépetl in central Mexico during the 5-day period from 21 May – 25 May 2023. On 21 May, the airport at Puebla (MMPB) was temporarily closed, due to the potential adverse impact of volcanic ash to... Read More
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...
