Hi Karl,
It would be far clearer to me if the same construct established for mean wind velocity were applied to gust wind velocity and I would prefer it if the existing constructs (used for currents as well as winds) were left as they are. So, my preference would be for Stephane's suggestion to be accepted. Cheers, Roy. Please note that I partially retired on 01/11/2015. I am now only working 7.5 hours a week and can only guarantee e-mail response on Wednesdays, my day in the office. All vocabulary queries should be sent to enquir...@bodc.ac.uk. Please also use this e-mail if your requirement is urgent. ________________________________ From: CF-metadata <cf-metadata-boun...@cgd.ucar.edu> on behalf of Stephane TAROT <stephane.ta...@ifremer.fr> Sent: 22 June 2017 12:56 To: cf-metadata@cgd.ucar.edu Subject: Re: [CF-metadata] Standard name for direction of wind gust Hi, I think it is better if the construction of this new standard name is similar with the construction of other ones. Of course we can discuss if we want to change all the existing from/to_direction standard_names, but it may take a lot more time to reach an agreement (On my side, I don't really have an opinion on the subject. from/to_direction may not be the best construction, but I think it is clear about what it represents) I hope that, for the moment, this discussion won't prevent the creation of this new standard_name !
