Dear Siobhan I've commented on most of your names, below. A general comment: standard names are case-sensitive and entirely in lower case.
> Sea_ice_albedo is already in the table > Sea_ice_thickness_in_sea_ice_categories > Sea_ice_area_fraction_in_sea_ice_categories The category is a kind of coordinate variable, so the standard names for these should be sea_ice_thickness and sea_ice_area_fraction, with some appropriate coordinate variable. Is it just an index or is it a physical quantity? > Surface_temperature_in_sea_ice Would surface_temperature be sufficient? > Temperature_at_sea_ice_snow_interface Could this be temperature_at_sea_ice_surface If not, I'd suggest temperature_at_interface_of_sea_ice_and_snow for clarity. > Sea_ice_age Could you define this? > Sea_ice_growth_due_to_* We have a standad name tendency_of_sea_ice_thickness_due_to_thermodynamics which is in m s-1. Your quantities are in kg m-2. I would suggest that a rate might be a more robust quantity i.e. kg m-2 s-1 because time-bounds are sometimes not supplied and without them a change is hard to interpret. We haven't got a name for sea-ice in kg m-2 at present. I'd suggest either sea_ice_amount like snow_amount, or sea_ice_mass_per_unit_area like the corresponding atmosphere name. Which do you (and others) think is better? Then we could have tendency_of_sea_ice_amount_due_to_thermodynamics in general - you haven't asked for this - and specifically tendency_of_sea_ice_amount_due_to_* where processes arre congelation, lateral_accretion and snow_ice_formation. Frazil is not a process - would the process be frazil_accretion? If you're sure that the change is better, not s-1, substitute change_in for tendency_of - we have a couple of change_in names in the table. > Sea_ice_melt_amount_at_ice_surface > Sea_ice_melt_amount_at_ice_base > Sea_ice_melt_amount_at_lateral_sides sea_ice_melt_amount in kg m-2 is like surface_snow_melt_amount, so that's consistent. We have _at_sea_ice_base in the table already, so I'd suggest sea_ice_melt_amount_at_sea_ice_surface sea_ice_melt_amount_at_sea_ice_base sea_ice_melt_amount_at_sides since sides are always lateral! > Sea_ice_total_heat_content This is probably analogous to integral_of_sea_water_potential_temperature_wrt_depth_expressed_as_heat_content which is in J m-2. The sea-ice quantity would be integral_of_sea_ice_temperature_wrt_depth_expressed_as_heat_content But you have J. Do you mean you integrate also over the entire area of sea-ice? If so, omit _content for a quantity in J; we use "content" to mean "per unit area" in many names. The reason for the long name is to emphasise that the zero of heat content is arbitrary. It's really a temperature integral multiplied by a conversion factor. > Downward|Upward_shortwave|longwave_flux_at_sea_ice_surface How do these differ from surface_downwelling|upwelling_shortwave|longwave_flux which are already in the table? If you want to specify a mean over the sea-ice area only, this can be done by cell_methods. Similarly, I am not sure there's a need for sensible and latent heat fluxes. We already have surface_upward|downward_sensible|latent_heat_flux > Downward_sea_ice_freshwater_flux. Could you explain what this is? > Sea_ice_volume_transport_at_Fram_strait In your doc this is sea_ice_transport_at_fram_strait in kg s-1. For this I would propose sea_ice_transport_across_line, which is already in the table, with fram_strait to be named by a coordinate variable of region. For surface stresses, we already have surface_downward_eastward|northward_stress and downward_eastward|northward_stress_at_sea_ice_base Do these meet the need? > Eastward_internal_stress_at_sea_ice_base, > Northward_internal_stress_in_sea_ice Why are these at_sea_ice_base? By analogy with atmosphere_eastward|northward_stress_due_to_gravity_wave_drag for these "body forces" I would propose sea_ice_northward|eastward_stress_due_to_* where it might be due_to rheology, coriolis_acceleration, sea_surface_tilt. > Sea_ice_strain_rate_due_to_* Is strain rate a tensor? > Sea_ice_ridging_rate Could you define this? > Snow_density is already in the table > Snow_age Could you define this? > Snow_thermal_energy_content As above, integral_of_snow_temperature_wrt_depth_expressed_as_heat_content In this case, you have specified J m-2 i.e. content. ? Liquid_water_content_in_snow_layer is already in the table as liquid_water_content_of_snow_layer > Liquid_water_content_in_permafrost_layer > Liquid_water_content_in_active_layer by analogy _of_ rather than _in_ I'm aware that "active layer" is the term in use by experts in that area, but I would suggest that for the more general audience of CF standard names we need a more informative term. What about seasonally_frozen_soil_layer? > Temperature_profile_in_* I would say this quantity is soil_temperature where the "profile" is specified by its depth coordinate. > Land_ice_geothermal_heat_flux This is not specific to land_ice. Could we just have geothermal_heat_flux? > Surface_ice_melt_amount Suggest land_ice_melt_amount. > Superimposed_ice_formation_in_ice_sheet Could we consider tendency_of_land_ice_thickness_due_to_superimposed_ice_formation or tendency_of_land_ice_thickness_due_to_refreezing_of_melt_water which might be more self-explanatory? Or change_in if not tendency_of. > Runoff_flux_due_to_ice_sheet_melt To be precise and consistency with other names surface_runoff_flux_due_to_land_ice_melt > Land_ice_melt_rate_at_ice_shelf_base If it's an ice-shelf, I'm not sure it's land ice! But anyway ice_shelf is sufficient. Could it be ice_shelf_lwe_basal_melt_rate by analogy with the existing land_ice_lwe_basal_melt_rate > Marine_ice_accretion_rate_at_ice_shelf_base By analogy, I would propose tendency_of_ice_shelf_thickness_due_to_accretion_at_ice_shelf_base > Ocean_temperature_in_ice_shelf_cavity > Ocean_salinity_in_ice_shelf_cavity > Ocean_temperature_at_ice_shelf_cavity_front > Ocean_salinity_at_ice_shelf_cavity_front The basic CF names are sea_water_temperature and sea_water_salinity. It seems to me that the cavity is a kind of geographical location - I'm not sure if it's necessary to include it in the standard name. On the other hand, you could say it was like a named surface or layer. Hmm - tricky. > Surface_orography_at_ice_sheet_surface. The standard name is surface_altitude. Again, cell_methods could be used if you specifically wanted a mean over land-ice area only.
