Re: [CF-metadata] seeking CF name for total water column height

Dear Jeff, Thank you for your standard name proposal for water column height and thanks to all who have contributed comments to this discussion. The consensus view seems to be that > sea_floor_depth_below_sea_surface is an acceptable name for this quantity and that it is consistent with the exist

Hello Alison, There are a lot of potential reference datums. I have a vocabulary containing 31 examples plus two nulls (http://vocab.ndg.nerc.ac.uk/list/L111/current or http://seadatanet.maris2.nl/v_bodc_vocab/search.asp?name=(L111)%20Vertical+Co-ordinate+Reference+System+Origins&l=L111 in pla

Hi Alison, *About the 'water level' vs 'sea surface height' In the case of Jeff needs would only concern ocean data, would you mind if I ask CF to introduce both? I was about to ask CF for such quantities on rivers and lakes.. *About reference datum, my opinion is that considering CF sta

Thank you for the discussion and current status regarding sea_floor_depth_below_sea_surface as a new standard name. I have changed the subject line of this email to focus on the other names we discussed. I have also CCed our local water level expert (Andrea Hardy from NOAA CO-OPS); my replies

Dear Jeff, Alison et al. Like Alison, I prefer sea_surface_height to water_level, because it's really the same geophysical quantity at the coast and far from the coast, isn't it. It seems awkward to me to say that the satellite altimeter measures SSH, while a tide gauge measures water level. The a

The term 'water_' is preferable to me too. When this liquid occurs underground, it still is appropriate to measure this quantity (and temperature, and other things). And when it occurs in the atmosphere, I don't think the term has any meaning -- measuring the height of atmospheric water is
