Dear Steve I would prefer keeping the sea_water in sea_water_pressure: > sea_water_pressure_at_the_sea_water_surface > sea_water_pressure_at_sea_floor It might seem redundant in this context but it corresponds to the standard name of sea_water_pressure, analogous to air_pressure. That means the pressure that exists in the medium of sea water. It doesn't imply that it is caused only by overlying sea water.

When we had the earlier discussion, I proposed temperature flux because I think that temperature multiplied by mass flux is a quantity that people have to be careful with because of its arbitrary zero. In that respect it is not like a genuine heat flux. You can't tell what heat is being added unless you know the temperature and the mass of the water it's being added to. I thought "temperature flux" would draw attention to the way it was evaluated. To be more explicit, it is product_of_rainfall_temperature_and_rainfall_flux_expressed_as_heat_flux Without expressed_as_heat_flux it would be in K kg m-2 s-1 rather than W m-2. Maybe it's OK to omit _into_sea_water since rainfall flux is generally assumed to be at the surface, and this quantity exists equally over land. We would use cell_methods to restrict it to the sea part of the gridbox. The definition should also state what the zero of temperature is. Why do we want these quantities? Would be clearer and easier to ask for the rainfall_temperature and the temperature_of_water_flux_into_sea_water_from_rivers? I'm sorry that I hadn't thought about the evaporation before. I'm not sure what this means: isn't the evaporating water necessarily at surface temperature? The heat carried away is just the latent heat.
