Robert,

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
interesting
document - page 7 details the various channels that MSG senses in and gives a
description of what the channels 'show.'

Regards,
John Tellick.

Thanks John - this looks very much like the glossy brochure we were given at
Leicester. I suppose I was hoping for some more technical advice - may be what
I am looking for should come from the meteorologists rather than EUMETSAT.
Best wishes
Robert
