Dear Jeff Thanks for your email. I appreciate your arguments, which are very reasonable, but I don't agree with them so far. > Replacing 'sea_' with something else seems like it would > break much existing code. Adding some names should be mostly harmless. Yes, adding names is better. We can re

Dear CF group: Thank you for your time in discussing this matter. I would counsel you *not* to make wholesale changes to existing names just because IOOS needs names for water levels that may or may not be measured in the ocean! Replacing 'sea_' with something else seems like it would break mu

Dear Stephen The issue here is that water doesn't only exist in these "bodies" of water viz seas, lakes and river. It also exists in the atmosphere and the ground. For this reason we don't have a standard name of just "water temperature", for instance. We could define "aqua" to mean "sea, lake or

Hi Roy, For sure, I wasn't proposing use of the word 'sorl', that was merely an examplar. My argument was that since there appears to be no existing term for what you want to describe - at least none without overloaded meaning(s) - then just invent a completely new word. So, yes, by its very natur

If I may make a suggestion that maintains the classical etymology and intuitive understanding ... the characteristic that applies to all of these water bodies is that they are water. Hence, I suggest that 'aqua' is both short, descriptive and pertinent. Kind Regards Steve -- Dr Stephen Emsley

Hi Phil, Jonathan's argument against 'water body' was that it was not as well-known as 'sea'. I think that the argument applies even more strongly to 'sorl'. Cheers, Roy. -Original Message- From: Bentley, Philip [mailto:philip.bent...@metoffice.gov.uk] Sent: 23 February 2010 09:25 To:

Hi Roy, Would simply inventing an artificial new term to represent sea+lakes+rivers be an option here? Presumably, back in the day, there was no word for a land-locked body of fresh water so someone thought, I know, I'll call it a 'lake'. Or whatever the latin/greek equivalent was back then! So w

Hello again, I wouldn't recommend using '/' in a string, such as a Standard Name, that could potentially be incorporated into a URL. I think using 'sea' as defined shorthand for 'river/lake/sea' has been suggested before. I certainly have no problem with it as long as that information is inc

[CF-metadata] two anomalous standard names

Dear Alison I suggest that these two standard names should be amended: moles_per_unit_mass_of_cfc11_in_sea_water -> moles_of_cfc11_per_unit_mass_in_sea_water The latter order is followed by all the other names i.e. moles_of_X_per_unit_mass_in_sea_water change_over_time_in_atmospheric_wate
