It's always recommended to include cell_methods, because the default depends
on whether the quantity is intensive or extensive in the dimension concerned,
and that may not be obvious. If it's not "point", it should be "sum". That
method (Appendix E) means it applies to the cell as a whole.

It would be great if someone had the energy and interest to summarise this
discussion as a FAQ to be addded to http://cfconventions.org/faq.html,
because it's likely it'll be asked again, since it's been asked before!

Best wishes

Jonathan
