Ah, I see. For > 3. ocean_steric_height_above_sea_level (m) I would suggest > The ocean steric height above sea level measures the change in thickness of a > column of water when its temperature and salinity are changed from standard > values of 0°C and 0.035 to the actual values > The bottom pressure equivalent height is estimated indirectly as the > difference between the steric height and the sea level. I don't follow that, which sounds like the definition of ocean steric height again. However your alternative statement of its being the mass of the column makes sense to me. Going with the latter definition, I would suggest sea_water_mass_per_unit_area_expressed_as_thickness and presumably you have to state a standard density to be used in this conversion - what is that? NB sea_water_mass_per_unit_area (kg m-2) is already a standard name. > 2. Instead of "ocean_turbocline_depth (m)" we suggest: > ocean_turbocline_thickness (m) > 'The turbocline thickness is similar to the mixed layer thickness but is > estimated in models as the thickness at which the vertical eddy diffusivity > coefficient (resulting from the vertical physics alone) falls below a given > value defined locally.' Is there a difference between that and the existing ocean_mixed_layer_thickness_defined_by_vertical_tracer_diffusivity ? > ratio_of_sea_water_potential_temperature_anomaly_to_relaxation_timescale (K > s-1) > > 'This term is estimated as the deviation of the local sea water potential > temperature from an ocean model wrt an observation-based climatology (eg > World Ocean Database) weighted by a user-specified relaxation coefficient in > s-1 (1/(relaxation timescale)).
