Re: [CF-metadata] Ocean content tendencies due to sedimentation -- sign ambiguity in CMIP usage

2018-09-05 Thread John Dunne - NOAA Federal
Hi Martin, I see your point. The tendency definition certainly argues for negative values for sedimentation and a change of "Loss to sediments" to something like "Tendency with respect to sedimentation" for consistency. Cheers, John On Wed, Sep 5, 2018 at 5:05 AM, Martin Juckes - UKRI STFC < ma

Hi Matthias, I'm going to have to go with in-situ, unless someone can correct me otherwise. I'm 86.33% confident, however. I have been looking at Jim Orr's documentation ( http://www.geosci-model-dev-discuss.net/gmd-2016-155/gmd-2016-155.pdf), and it cites: Dickson, A. G., Sabine, C. L., and Ch

Is the plan also to demote the "silicate" and "phosphate" names? That would seem to make sense to me, consistent with Jim's points. On Fri, Mar 24, 2017 at 12:13 PM, wrote: > Dear Jim, > > thanks. I think that means that we need a corrections to the statements, > from the CF Standard Name list,

A couple of questions... 1) Regarding the request to add Chlorophyll_a fluorescence, the proposed unit is kg/m3, but shouldn't fluorescence have radiation units (i.e. Watts/m2)? I was not aware that any of the proposed CMIP models treated fluorescence explicitly, but if that were the case, it wou

I like the idea of appending "growth" to those limitation names - makes sense. On Thu, Oct 20, 2016 at 1:06 PM, Jonathan Gregory wrote: > Dear John and Alison > > I think the definition of limitation is fine for the names. However I do > still > have a slight concern that "limitation" alone is n

The attempt to as sea surface - SS prefixes was only to follow the convention as my understanding was that the convention could not handle two variables with the same name but different dimensions. If that is not truly a problem on your end, then perhaps it is a non issue. On Thu, Oct 20, 2016 at
