Hi Andy
Many of the sea_surface_height terms have been used in satellite altimetry for some time.
The tidal components have been split out into
sea_surface_height_amplitude_due_to_equilibrium_ocean_tide<javascript:void(0)>
sea_surface_height_amplitude_due_to_geocentric_ocean_tide<javascript:void(0)>
sea_surface_height_amplitude_due_to_non_equilibrium_ocean_tide<javascript:void(0)>
And the pole tide
sea_surface_height_amplitude_due_to_pole_tide<javascript:void(0)>
In these terms, amplitude has been used to identify the ?above mean level? and sea_surface_height is as alias of sea_surface_heigth_above_mean_sea_level
Also included are the terms
sea_surface_height_correction_due_to_air_pressure_and_wind_at_high_frequency<javascript:void(0)>
sea_surface_height_correction_due_to_air_pressure_at_low_frequency<javascript:void(0)>
The former of which is related to surge I think - it is normally determined from a tidal model and is the response of sea level to changes in air pressure and wind.
Even if these are not the correct terms, as you are not determining a 'correction? but a value - they should be related to the surge components, so do they give the ?due to? component you need?

Dear all,
First posting to this list, so please forgive me if I?m doing it wrong?
I?d like to request an addition to the standard name list to include storm surge residual and tide. These variables are generated for the purpose of coastal flood prediction and will be available in future, netCDF based, operational products from the Met Office.
Proposed standard name: sea_surface_height_above_mean_sea_level_due_to_storm_surge
Units: m
"Sea surface height" is a time-varying quantity. "Height_above_X" means the vertical distance above the named surface X. "Mean sea level" means the time mean of sea surface elevation at a given location over an arbitrary period sufficient to eliminate the tidal signals. The specification of a physical process by the phrase ?due_to_process? means that the quantity named is a single term in a sum of terms which together compose the general quantity named by omitting the phrase. Storm surge effects, due to meteorological forcing of the ocean and interaction between the generated surge and tides, are a significant contributor to the observed sea surface height.

Tides are a significant contributor to the observed sea surface height; here ?tide? denotes a generic variable describing the time varying tidal signal, for example as generated based on a summation of harmonically analysed components, or resulting from the application of such components as boundary conditions to a numerical tidal model.
Many thanks
