# [CF-metadata] New standard names for OMIP: physics

Dear Alison   cc Steve, Paul

Sorry for slow response. I've read Steve's edited version and I agree with
your and Steve's proposals. Thanks. Changing all the integral_of_X_wrt_Y to
integration_wrt_Y_of_X will make them more readable, I think, and it's a
neater construction. In fact people sometimes write \int dy X intead of
\int Y dx in mathematical formulae, because it's natural to think of \int dy
as an operator.

Regarding the residual_mean_advection names, I agree that this is what we
want for OMIP and FAFMIP. However if you search for due_to_advection you will
find quite a few existing ocean ones e.g.
(K s-1). Is it clear in the definitions what sort of advection this is (I am
offline and cannot check)? I believe that in these existing names we mean
mean residual mean advection. Maybe it would be a good idea to change
this means advection by the model's sea water velocity field, not including any
parametrised subgridscale advection. In the atmos we also have some due_to_
so there's not the same issue.

If you agree with that, I would also advocate including new standard names
like 3n,o,p but with resolved_advection. They are not needed for the CMIP6
request, but they probably are useful. I'd use them for NEMO and UM ocean
model diagnostics, for example!

Best wishes
