[CF-metadata] can a cell method be an attribute of an auxiliary coordinate variable ?

Dear Jim

Yes, I think such an approach is applicable. Any data variable can have
cell_methods and any data variable could be used as an aux coord variable.
Although unusual, I don't see a reason not to have data variables of latitude
and longitude, qualified by cell_methods, if required.

Best wishes

Jonathan

> So, I?ve got a broader question. We have a case in hand with trajectory data for a physically extensive weather system. Two data variables are the mean longitude and latitude of the system, which we are treating as the auxiliary coordinate variables. Other data variables contain measurements such as maximum latitude at the mean longitude, etc. Are cell_methods applicable in this case? There is no grid, so the cell would be the area covered by the system, and the extents of this area are not described.
