Re: [CF-metadata] water level with/without datum

Hello Jonathan, I have concerns about having separate names for river, lake and sea. If you have them for height, then the logic would extend to temperature. I have temperature data from a boat that started in the North Sea, went up the Humber and then up to the navigable limit of the

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

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

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

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 river,

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

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
