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...

10-minute Full Disk sector GOES-18 (GOES-West) Day Land Cloud Fire RGB, Shortwave Infrared (3.9 µm), “Clean” Infrared Window (10.3 µm) and “Red” Visible (0.64 µm) + Fire Power derived product (a component of the GOES Fire Detection and Characterization Algorithm FDCA) images (above) showed signatures of multiple wildfires across northeastern British Columbia (BC) and northwestern Alberta (AB), some of which...

Daily imagery from the CSPP Geosphere website above, at 0400 UTC from 12-19 September, show haze (highlighted by the blue arrows) moving across the Pacific Ocean. The haze is likely a by-product of the ongoing eruption at Kilauea. The initial burst of haze moved beyond the view of GOES-West by 19 September, but imagery shows... Read More
10-minute GOES-18 (GOES-West) “Red” Visible (0.64 µm) + Fire Power derived product (a component of the GOES Fire Detection and Characterization Algorithm FDCA), Shortwave Infrared (3.9 µm), “Clean” Infrared Window (10.3 µm) and Day Land Cloud Fire RGB images (above) showed a wildfire east of Fort Nelson (CYYE) in far northeastern British Columbia that produced 3 consecutive pyrocumulonimbus (pyroCb) cloud pulses late...
