As you know MSG satellites will observe the Earth in 12 spectral channels.
Each channel has the ability to detect/show various features.
If you go to the EUMETSAT website and look for document EUM BR 11 -
Applications of Meteosat Second Generation - a very informative and
document - page 7 details the various channels that MSG senses in and gives a
description of what the channels 'show.'
