Dear Roy,
I would suggest that this is more in scope for GitHub than a Standard Name discussion as changes to the Conventions document could be required. Why not take it forward there and see if you can engage some interest? I also feel that this could take some time and do not feel it would be fair to block Simon's request until it is resolved. There are a number of anomaly Standard Names and one more isn't going to make a great deal of difference. Cheers, Roy. I have now retired but will continue to be active through an Emeritus Fellowship using this e-mail address. ________________________________ From: Roy Mendelssohn - NOAA Federal <[email protected]> Sent: 05 December 2018 14:35 To: [email protected] Cc: Lowry, Roy K. Subject: Re: [CF-metadata] Sea water temperature anomaly standard name Interesting. Look at the archive around April 4, 2016. I was requesting a standard way to do anomalies, not just variable specific, since anomalies are calculated all over the place, and it seems to me it makes little sense to have a new name for each specific anomaly, rather than a generic method based on an existing name. Let us just day it was not greeted with open arms. Perhaps this is worth revisiting. -Roy M. > On Dec 5, 2018, at 6:20 AM, Lowry, Roy K. <[email protected]> wrote: > > Hello Simon, > > If you look at the definition for > ocean_mixed_layer_thickness_defined_by_temperature you will get a better > understanding about what sea_water_temperature_difference is about.
