GOES-16 (GOES-East) “Red” Visible (0.64 µm), Shortwave Infrared (3.9 µm) and “Clean” Infrared Window (10.3 µm) images (above) showed the formation of 2 pyrocumulonimbus (pyroCb) clouds that were created by a fire complex in northeastern Bolivia on 22 October 2023. The coldest cloud-top 10.3 µm infrared brightness temperature of the first (larger) pyroCb was around -56ºC... Read More

MIMIC Total Precipitable Water (TPW) fields, below, show a band a rich moisture over the northern Indian Ocean between the Equator and 15oN Latitude. By 17 October in the animation, cyclonic motion is diagnosed in the TPW fields between 60o and 70o E Longitude. By 18 October, an invest was... Read More

Strong gap winds accelerating out of the Copper River Valley — located along the coast of southcentral Alaska — were lofting fine particles of glacial silt/sand, and transporting those aerosols southward across the Gulf of Alaska during 20-22 October 2023. 10-minute GOES-18 (GOES-West) Dust Red-Green-Blue (RGB) images created using Geo2Grid (above) displayed the...
