Comment (by jonathan):

 Dear Martin

 Thanks for the proposal. It seems to me that this is probably going a bit
 beyond the role of CF metadata, which is to describe what the data is i.e.
 the mean within sea-ice areas - that's a sufficient description to
 distinguish it from other quantities for most purposes. Your aim here is
 to provide more information about how it was calculated, perhaps to enable
 further calculations. That could be done, but I'm not convinced of the
 case for providing special CF metadata for it unless it's an important
 use-case. An alternative would be to record this information in some
 unstandardised attribute, such as the history, which is where people do
 sometimes record how variables were calculated. This could be standardised
 by a CMIP6 convention, of course, in which there is a more systematic
 relationship between quantities requested.

 Best wishes

 Jonathan
