Hello Jonathan,
here are a few names we need to represent some of the HiGEM/HadGEM data
tendency_of_air_temperature_due_to_advection: K s-1
tendency_of_specific_humidity_due_to_advection: s-1
tendency_of_eastward_wind_due_to_advection: m s-2
tendency_of_northward_wind_due_to_advection: m s-2
tendency_of_upward_air_velocity_due_to_advection: m s-2
tendency_of_mass_fraction_of_cloud_liquid_water_in_air_due_to_advection: s-1
tendency_of_mass_fraction_of_cloud_ice_in_air_due_to_advection: s-1
tendency_of_air_temperature_due_to_diffusion: K s-1
tendency_of_specific_humidity_due_to_diffusion: s-1
tendency_of_eastward_wind_due_to_diffusion: m s-2
tendency_of_northward_wind_due_to_diffusion: m s-2
tendency_of_mass_fraction_of_cloud_liquid_water_in_air_due_to_diffusion: s-1
tendency_of_mass_fraction_of_cloud_ice_in_air_due_to_diffusion: s-1
surface_mass_flux_of_sulfur_dioxide_due_to_emissions: kg m-2 s-1
mass_flux_of_sulfur_dioxide_due_to_emissions: kg m-2 s-1
surface_mass_flux_of_dimethyl_sulfide_due_to_emissons: kg m-2 s-1
