GOES-16 SO2 RGB images, from 0500-2100 UTC on 03 March [click to play animated GIF | MP4

GOES-16 (GOES-East) SO2 RGB images created using Geo2Grid (above) showed the volcanic cloud (lighter shades of cyan) resulting from an eruption of La Cumbre in the Galápagos Islands on 03 March 2024. The thermal anomaly at the volcano summit — which first became apparent at 0550 UTC — appeared as clusters of darker blue pixels.

A comparison of SO2 RGB and retrieved Ash products from the NOAA/CIMSS Volcanic Cloud Monitoring site (below) indicated that this particular volcanic cloud was entirely SO2-dominated, with no signature of ash content.
