Dear Jonathan, I appreciate the idea suggested by Philip, which is remove 'local' and simply use "tendency_of_average_sea_level_change". I think it's a fine solution.
Concerning amplitude and phase I agree with you. We could use 'amplitude_of_X' and 'phase_of_X' in the standard names, and describe the period (or frequency) in a coordinate variable. Cheers Olivier. -----Message d'origine----- De : CF-metadata [mailto:[email protected]] De la part de Jonathan Gregory Envoyé : vendredi 6 juillet 2012 13:50 À : [email protected] Objet : Re: [CF-metadata] Standard names for sea level change Dear all Regarding the existing standard_name global_average_sea_level_change and the corresponding ones for steric and thermosteric: It is anomalous to have "global" and "average" in a standard name because, as Philip says, we usually put these kinds of thing in cell_methods. The reason for having them in the standard name in these cases is that these global quantities are commonly referred to without being regarded as the global average of something. You can imagine other quantities which refer to the whole world; for example we might have a standard name for the age of the Earth. Although it's a fuzzy distinction, it's not quite like global average air temperature change, for example. We do not have a standard name for that, because people do regard it as the global average of local air temperature change. That is how it is computed. Global average sea level change, before satellite altimetry began, is estimated from sparse measurements by various methods. However, we could change to using more systematic names, although it would be a bit more obscure. global_average_sea_level_change could be described by a standard_name of change_in_ocean_thickness with cell_methods of "area: mean over sea" for the whole world. global_average_thermosteric_sea_level_change could be change_in_ocean_thickness_due_to_thermosteric_change. Should we make that change (with aliases)?
