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...

The Imager on GOES-13 captured approximately 2,307,267 images (counting each of the 5 spectral bands as an image), with an additional (at least) 264,480 images as EWS-G1 — for a total of 2,571,747 images! In addition, the GOES-13 Sounder captured 3,054,820 images (counting each of the 19 spectral bands as... Read More

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
