Dear Ian > So, apart from T14, I think we're agreed.
Splendid. On T14, I'll agree with you that it is helpful to indicate what sort of depth it is. The fact that it is the depth of an isotherm is a main point of the definition of the quantity, whereas temperature on sigma levels and temperature on pressure levels are really the same quantity, just like temperature on a lat-lon grid and temperature on a tripolar grid are the same quantity. However I'd like to suggest an alternative to ocean_isotherm_depth. What do you think of depth_of_isosurface_of_sea_water_temperature? This is of course not the common term but my aim is not to be obscure. I am thinking of (a) precision; "isotherm" might mean potential or in-situ temperature, I guess. (b) generality. Any quantity that is defined as a function of z might be inverted in this way. While "isotherm" is a fairly familiar word, we don't want to have to depend on the existence of a Greek-based "iso" word in order to name a quantity. Does "isosurface" have an obvious meaning to you? It turns out to be a word that is in common use with this meaning e.g. IDL and ncar graphics both use the term, and it's in wikipedia. If this is too user-unfriendly I'll settle for ocean_isotherm_depth and if we have later problems we can sort it out with aliases.
