Dear Jonathan,
Thank you for your advices; we'll use the cell_methods as suggested. For
diffusivity, we'll use " ocean_vertical_diffusivity" as standard_name
because I agree it may be enough.
Thus my request would only concern adding a new standard name:
ocean_vertical_diffusivity, expressed in m2s-1, and that would be defined by
"vertical diffusivity due to instability in ocean".
Thanks,
Merry Christmas to all
Olivier.

We still want to indicate the statistical method, so it would be for
instance
cell_methods="area: mean where sea_ice".

Yes, diffusivity is fine, of course, as a general concept. I was wondering
whether you meant something specific by "eddy". Another way to ask the
question is, why not call it just ocean_vertical_diffusivity (and perhaps
instead "heat" or "momentum" if they have different values)?
Best wishes
Jonathan
