Dear all, Just to mention that in principle ocean_vertical_diffusivity should be already available within CF standard name table, I remember we discussed on this last Christmas.

I wanted to discuss your question with our ocean modeller and couldn't reach him until today. This is his answer: > > > Could you describe > > > what you mean by "due to wind" in the case of diffusivity? > > > > "due_to_wind" means induced by winds on the surface. > > Do you mean wind-driven mixing (in the mixed layer) is represented by a > diffusion scheme, and you have other diffusion schemes (with different > diffusivities) for interior mixing resulting from other kinds of > turbulence? "As default we use Richardson-Number depended mixing following Pacanowski and Philander plus an additional wind induced mixing term which decays exponentially with depth . Both is included in ocean_vertical_diffusivity, however the wind induced part can be diagnosed separately (ocean_vertical_diffusivity_due_to_wind)." Maybe, it would be clearer to use "due_to_wind_mixing" instead of "due_to_wind". Which one is more precise/understandable? > > > > 1. richardson_number; 1 > > > > > > I'd suggest this should be richardson_number_in_sea_water since it > > > could also be defined in air.

And yes, we agree on the unit in the standard name table. To sum up our altered proposal: richardson_number_in_sea_water; 1 ocean_vertical_viscosity; m2 s-1 ocean_vertical_diffusivity; m2 s-1 ocean_vertical_diffusivity_due_to_wind or ocean_vertical_diffusivity_due_to_wind_mixing; m2 s-1 water_flux_into_ocean_without_flux_correction; kg m-2 s-1 Can we agree on the names for the two energy tendencies? We haven't discussed them so far. 4. energy tendencies tendency_of_potential_energy_content_of_ocean_layer_due_to_diffusion; W m-2 tendency_of_potential_energy_content_of_ocean_layer_due_to_convection; W m-2 Regarding the "where_sea" parameters, we wait for the decision of ticket 17? 5. some "where_sea" parameters surface_net_downward_radiative_flux_where_sea; W m-2 surface_net_downward_shortwave_flux_where_sea; W m-2 surface_net_downward_longwave_flux_where_sea; W m-2 surface_downward_latent_heat_flux_where_sea; W m-2 surface_downward_sensible_heat_flux_where_sea; W m-2 Best wishes, Martina _______________________________________________ CF-metadata mailing list [email protected] http://mailman.cgd.ucar.edu/mailman/listinfo/cf-metadata Cliquez sur l'url suivante https://www.mailcontrol.com/sr/xEy5rmkU8AvTndxI!oX7UsdzF!uV4N23XX5SuipGe4Pu5aNoHjz3XxhC+LmkqWuQfyt4IvpuMOzbd8XIx2vetQ== si ce message est indésirable (pourriel). _______________________________________________ CF-metadata mailing list [email protected] http://mailman.cgd.ucar.edu/mailman/listinfo/cf-metadata
