EUMETSAT Meteosat-11 False Color RGB images from the NOAA/CIMSS Volcanic Cloud Monitoring site (above) showed the signature of a volcanic cloud associated with an eruption of Mount Etna on 19 February 2021. The brighter shades of red/magenta suggested the presence of ash within the volcanic cloud. This was supported by high values of retrieved Ash Loading (below).

A Meteosat-11 Ash Effective Radius Product (below) depicted rather large ash particles, generally in the 14-16 µm range.

A Meteosat-11 Ash Height product (below) showed retrieved values up to 12-13 km (magenta enhancement) for parts of the volcanic cloud.

Another version of Meteosat-11 False Color RGB images which use 8.7 µm data (below) revealed shades of green that indicated a higher concentration of SO2 within the southern portion of the volcanic cloud.
