1-minute Mesoscale Domain Sector GOES-18 (GOES-West) daytime True Color RGB + Nighttime Microphysics RGB images from the CSPP GeoSphere site (above) showed a plume of resuspended volcanic ash (hazy shades of gray in True Color RGB, and brighter shades of pink in Nighttime Microphysics RGB) from the 1912 Novarupta-Katmai eruption in Alaska, which was being transported offshore across the Shelikof Strait toward Kodiak Island on...

Overlapping 1-minute Mesoscale Domain Sectors provided 30-second interval GOES-16 (GOES-East) Day Land Cloud Fire RGB images (above) that included an overlay of Fire Power and Fire Mask derived products (2 components of the GOES Fire Detection and Characterization Algorithm FDCA) — which showed the thermal signature and dark black smoke plume associated with a fire at the...

GOES-16 (GOES-East) “Red” Visible (0.64 µm) images (above) showed a narrow (2-4 miles in width) plume of smoke+fog — the smoke was from a marsh fire burning near New Orleans East — that was moving to the northwest across Lake Pontchartrain after sunrise on 07 November 2023. This dense smoke+fog plume rapidly reduced... Read More

GOES-16 (GOES-East) SO2 RGB and Ash RGB images (above) showed a remnant volcanic cloud from the 31 October Klyuchevskaya eruption as it moved over southern Saskatchewan, northern North Dakota and far northwestern Minnesota on 06 November 2023. The volcanic cloud exhibited brighter shades of orange-yellow in the SO2 RGB imagery, and darker shades of blue in the... Read More
