Hi Nan, Using unqualified 'water' to signify water within a water body works for me.
Cheers, Roy. -----Original Message----- From: cf-metadata-boun...@cgd.ucar.edu [mailto:cf-metadata-boun...@cgd.ucar.edu] On Behalf Of Nan Galbraith Sent: 25 February 2010 16:47 To: Jonathan Gregory Cc: John Graybeal; cf-metadata@cgd.ucar.edu Subject: Re: [CF-metadata] water level with/without datum Agreed, water_surface_height_above_x is perfect. And simple, as Jeff pointed out earlier this week. > I think Roy's example is a relevant use case.

I'd like to extend the use of this prospective term to sub-surface water bodies, which, like rivers, don't always have clear boundaries. We have ROVs that travel from lakes and reservoirs through subsurface passages; I don't see any reason to (or reasonable way to) split up the measurements made by these instruments based on which side of an invisible line they're on at any given point. So, I think 'water' is far better than 'sea_lake_river_water'. There are several names that use the modifiers 'atmosphere', 'in_air' and 'surface' to indicate water that's not part of a water body. Does this imply that the unmodified term 'water' means water that's in a water body? The only names I can find that use plain 'water' seem to be sound_intensity and sound_pressure terms - I assume these refer to water in a water body? Is that enough of a precedent to suggest that water_temperature, _velocity, _salinity, etc etc could be standard names for properties of the water in bodies of water?
