Hi Jonathon and CF metadata list, Summarising our discussions thus far we propose:
2 new Cell methods: root_mean_square mean_of_upper_decile and these new standard names: sea_surface_wave_height (common concept) sea_surface_wave_mean_crest_period sea_surface_wave_significant_wave_period sea_surface_wave_period_at_second_largest_peak_of_variance_spectral_density sea_surface_wave_variance_spectral_density_zeroth_frequency_moment sea_surface_wave_root_mean_square_amplitude_from_variance_spectral_density The sea_surface_wave_height is a common concept (standard name) which may bequalified by a cell_method attribute to realise the actual variable. The sea_surface_wave_height
when combined with a cell method of: time: mean time: maximum time: root_mean_square time: mean_of_upper_decile will describe the statistical wave height variables: sea_surface_mean_wave_height sea_surface_maximum_wave_height sea_surface_root_mean_square_wave_height sea_surface_wave_mean_of_highest_one_tenth_waves respectively. I have attached a spreadsheet which contains the names, descriptions and units of the variables proposed. Looking forward to getting final approval to add these to the CF name lists.

Dear AndrewYes, but depends on the community (list) accepting the idea of having aGood. I think we are agreed then to propose these new cell methods: root_mean_square mean_of_upper_decile and these new standard names: sea_surface_wave_height sea_surface_wave_mean_crest_period sea_surface_wave_significant_wave_period sea_surface_wave_period_at_second_largest_peak_of_variance_spectral_density sea_surface_wave_variance_spectral_density_zeroth_frequency_moment sea_surface_wave_root_mean_square_amplitude_from_variance_spectral_density I agree that the last will avoid confusion with the RMS of wave height. I agree also that this depends on users being comfortable with the concepts being split into two attributes, in accordance with the usual CF practice, but deciding on how to join them up as common_concepts will help. Comments from others would help. It is good that Roy supports this compromise. Best wishes Jonathan
