Dear all, for the output parameters of our ocean model MPI-OM we identified a few parameters for which no CF standard name could be found.
We propose to add to the CF convention: 1. richardson_number; 1 This number is used in meteorology as well as in oceanography. It is the dimensionless ratio of buoyant suppression of turbulence to shear generation of turbulence. It is used as a dynamic stability measure to determine if turbulence will exist (AMS-Glossary http://amsglossary.allenpress.com/glossary/search?id=richardson-number1). 2. viscosity and diffusivity measures: sea_water_vertical_viscosity; m2 s-1 sea_water_vertical_diffusivity; m2 s-1 sea_water_vertical_diffusivity_due_to_wind; m2 s-1 Diffusivity is used for tracers, i.e. temperature and salinity, and viscosity for momentum. Viscosity is defined as the ratio of the shearing stress to the shear of the motion. 3. water_flux_in_ocean_without_flux_correction; m s-1 [kg m-2 s-1] We have an uncorrected water_flux term. In the existing and referenced water_flux_into_ocean this correction is already contained. Since this water flux is used for freshwater (of density 1 kg m-3) the unit can be either the CF flux unit kg m-2 s-1 or the one used in our ocean model m s-1. 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 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 These are only needed if ticket 17 (I hope the number is right. I got an error on the trac site when I tried to check it.) should be unsuccessful. Otherwise the addition "where_sea" will move into the attributes. And for the "remaining parts" there already exist CF standard names.
