Re: [CF-metadata] sea water speed and direction?

Dear John, That's a good point about the ambiguity of 'direction_of_sea_water_velocity'. As an observational oceanographer its built into my core program that 'direction' means 'direction_to' for currents. I'm not alone here, which is probably how the ambiguity got overlooked when the Standard

Dear John and Roy direction_of_X is a construction in the standard name table, and I believe it's assumed it's a to_direction. For wind, which is the oldest vector in the table, we have to_direction and from_direction because of the potential confusion of e.g. westerly and westward wind. Is there

Dear Jonathan, For years - even the odd decade - I believed 'direction' and 'direction_to' to be 100% synonymous for currents. However, I can recall current meter data delivered to BODC in the late 90s with channels labelled 'speed' and 'direction' where QC showed that the direction was in fac

Thanks, Roy. I'm happy with all of your recommendations. If they become implemented, I would appreciate a notice. Aloha, John On Thu, Jun 1, 2017 at 11:20 PM, Lowry, Roy K. wrote: > Dear John, > > > That's a good point about the ambiguity of 'direction_of_sea_water_velocity'. > As an observation
