Thank you for your proposal. These terms will be added to the cfeditor (http://cfeditor.ceda.ac.uk/proposals/1) shortly. Your proposal will then be reviewed and commented on by the community and Standard Names moderator.
Dear @JonathanGregory,
Thank you for your work in putting together this comprehensive list!
I've had a look through this list and tried to identify which of the "new" names you mentioned have just been accepted in issues #285, #286, #287, #288 and #314, and which were are being proposed for the first time here (so need adding to the editor).
Here are the newly accepted (i.e. existing) names I found from those issues:
change_in_sea_surface_height_ due_to_change_in_air_pressure
ocean_dynamic_sea_level
tidal_sea_surface_height_above_mean_sea_level
(first new name for tides, from #287)change_in_sea_floor_height_above_reference_ellipsoid_due_to_ocean_tide_loading
(second new name for tides, from #288)global_average_steric_sea_level_change
(question below)Some points for discussion:
sea_surface_height_above_reference_ellipsoid_assuming_zero_air_pressure_anomaly_and_mean_tide
hasn't been officially proposed in the issue #285 (as mentioned in the table), but this can be added as a new name?
global_average_steric_sea_level_change
has just been accepted in #314. To be clear, you're proposing that this be changed to global_mean_steric_sea_level_change
. Should it be published first, then an alias created, to retain the old name?
The same goes for global_mean_sea_level_change_due_to_change_in_ocean_mass
which is currently accepted under global_average_sea_level_change_due_to_change_in_ocean_mass
.
Thanks again and looking forward to the reply.
Best regards, Ellie
Dear Ellie
Thanks for your careful checking! That's helpful.
tidal_sea_surface_height_above_mean_sea_level
and global_average_steric_sea_level_change
are existing standard names.
I agree that ocean_dynamic_sea_level
, change_in_sea_floor_height_above_reference_ellipsoid_due_to_ocean_tide_loading
and change_in_sea_surface_height_due_to_change_in_air_pressure
are new standard names that we've just accepted. Sorry about the hazardous space in the last of those, which was there only so that the table above folds itself into fewer lines.
global_average_sea_level_change_due_to_change_in_ocean_mass
is a newly accepted standard name, as you say. You are right that I would prefer global_mean_
... in this and some existing names, but that's only my proposal, which we have not yet discussed. Since Stéphane and colleagues may start using this name immediately, we should maybe introduce an alias for it, even if that happens in the same version of the table as its initial appearance, but I don't know if that's the best thing to do.
Stéphane and Aurore didn't need sea_surface_height_above_reference_ellipsoid_assuming_zero_air_pressure_anomaly_and_mean_tide
in the end, but I'll keep it in this proposal.
I have updated the table at the top of the issue to accord with these points.
Best wishes
Jonathan
I also vote for "mean", as opposed to "average".
Dear Jonathan,
Thank you for pointing out the existing names tidal_sea_surface_height_above_mean_sea_level
and global_average_steric_sea_level_change
. These have been removed from the corresponding issues #287 and #314. I've removed the extra spaces from these names.
I will update the editor with proposed changes to the existing names now. The 10 new names are visible here:

Dear Jonathan,
The 8 changes to existing standard names are now in the CF editor as 'under discussion', see the entries below:

to global_mean_sea_level_change_due_to_change_in_ocean_mass
at this time as this has yet to be published under the previous name and further discussion is needed around whether an alias would then be required.
Best wishes, Ellie
Thanks, Ellie @efisher008. I will soon write down the reasons for proposing these new and changed names, and the descriptions for them.
I would like to propose 11 new standard names and changes to 8 existing standard names, all relating to sea surface height and mean sea level. The aims of the proposal are
There are currently six other standard name proposals under discussion for sea level quantities, proposed by @abiardeau, @SwatiGehlot and @slawchune. The table below refers to the relevant open issues. In order to prevent confusion and complication, I think it would be better to delay discussion of my proposals until those ones are concluded, but I'm opening this issue now in case it's useful to see the set of names for related quantities. Comments are welcome, of course.
The following table shows the newly proposed names (new in the old standard name) column, the proposals for changed names, and for comparison some existing names that aren't proposed to be changed (unchanged). The new names will need definitions, which I'll fill in soon. I will base the definitions on those given by Gregory et al. (2019, https://dx.doi.org/10.1007/s10712-019-09525-z), which was used as a reference by the IPCC AR6. The column N in this table is the number of the quantity in that paper. All these quantities have
m
as canonical unit, except that the last one ism s-1
