Dear Ute Ah, I see the problem. OK. Yes, I would understand surface_Xward_sea_water_ velocity to mean the velocity of the water, not the ice. Best wishes Jonathan > This is a citation of the CF standard > > The surface called "surface" means the lower boundary of the atmosphere. > > "Water" me

Hi John, Totally agree with you about the confidence level and what people SHOULD be doing. However, I am uncomfortable with CF becoming a tool to force those who have quoted at standard conditions and used the existing Standard Name rework their data. However, should a formal approach from

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

Dear Alison, Thank you very much for taking your time to send the detailed reply to my proposal. I agree with most of the suggested improvements. I agree with you that 'sea_salt' is more appropriate than 'seasalt'. Feel free to change all proposed sea salt standard names to 'sea_salt'. Wr

Dear Matthias, My concern with your suggestion is that in effect you are asking for the the Standard Name + definition to be semantically narrowed. Should somebody have used the Standard Name without this clarification for corrected data then the proposed change would introduce a semantic erro

Matthias, Having talked to a number of scientists and data processing folks when trying to advance these proposals, it was clear that all different scenarios were possible. We tried to write the descriptions to describe the meaning of the value, without regard to the circumstances of the measur

Dear Roy, thank you for your helpful comment on the in-situ conditions. For the question about adding this information in some way, perhaps I had worded this ambiguously. I was more asking about updating the description (and not in fact the standard name). Best regards, Matthias On Thu, Jun

Dear All, This is a somewhat belated announcement of the most recent standard name table update. The current version is now V44, dated 23 May 2017. The changes have also been published in the NERC Vocabulary Server. They are listed in full at the end of this message. The next update to standar

Dear Daniel, Thanks for (re)proposing your names. First a couple of general points that are relevant to many of your sea salt names. In your original posting in March (http://mailman.cgd.ucar.edu/pipermail/cf-metadata/2017/059293.html) you pointed out that there are two existing names, mass_

Dear Sebastien, Thank you for once again bringing this back to the list. I agree that the discussion seems to have settled on the "steric" names rather than the longer versions. We need to have definitions, so I've modified the text I suggested previously. We now have: steric_change_in_sea_sur

Dear Matthias, All I can say that is that in-situ conditions were my assumption when involved in the initial discussions on this issue. However, I would not rely on the Standard Name to convey such detailed usage metadata information. Its function is to describe what was measured rather than t

[CF-metadata] Sea water pH values: at standard or in-situ conditions?

2017-06-08 Thread Matthias Tuma
Hello all, we had a question come up for the "sea_water_ph_reported_on_total_scale" standard name: it appears that for some communities, in particular on the measurement side, pH would regularly be reported only after first having converted to its equivalent at standard conditions (25C, 0dbar). In
