Re: [CF-metadata] [cf-convention/cf-conventions] DOIs for CF Convention releases? (#127)

2021-08-30 Thread Nan Galbraith
I agree that both the standard name table and the conventions document would probably need separate DOIs. We've gotten a DOI for the most recent version of the OceanSITES Data Format Manual. I believe that implies that we'll have to keep this version available in perpetuity, since new

2021-04-12 Thread Nan Galbraith
This looks very good, I appreciate all the work that went into it. I DO have a question (or 3) about how this could be applied to vectors (e.g. northward/eastward_sea_water_velocity or northward/eastward_wind), where there are uncertainties in both speed and direction, and the units for the

I also agree with Karl, however I was struck by the descriptions, e.g. 'Wind speed measured at 10 meter height'. Working with observational data, I'd be very interested to know if there's a standard way to indicate that a variable represents wind speed that was measured at 2 m and then

Re: [CF-metadata] [cf-convention/cf-conventions] Proposal: Add QARTOD quality flag names to standard name list (#216)

2020-02-04 Thread Nan Galbraith
This is all an improvement. I like Roy's change to the definition of the aggregate flag, 'an algorithmic combination of the results of all relevant quality tests', in place of 'set to the highest-level (worst case) flag found'. I DO have an issue with the term 'related ancillary parent data

Thank you Alison, this is all good. I DO have a couple of issues with this paragraph: 'This flag is a summary of all quality tests **run for another data variable**, which have standard names of the form X_quality_flag, and is **set to the highest-level (worst case) flag found**. Information

I'm afraid I'm the odd man out here - I don't think the list of benefits in the original issue stacks up against the costs; in fact some of them don't seem to BE benefits. Maybe some use cases would be helpful ... Could you elaborate on how this change would support international usage? Is

2020-01-08 Thread Nan Galbraith
The external files are fine, but there's one problem with using the 'references' attribute; that term is defined as a global attribute in CF. Most netCDF software does not handle a situation where a term is used as a global and a variable attribute the way you might expect - that's apparently

Re: [CF-metadata] [cf-convention/cf-conventions] Proposal: Add QARTOD quality flag names to standard name list (#216)

2020-01-07 Thread Nan Galbraith
I personally think including this level of detail (number of standard deviations, upper/lower limits, gap length, name of climatology used, distance to 'neighbor' data, etc) is beyond the scope of CF; there are just too many details. Every test has its own inputs, and these may vary with

2019-12-17 Thread Nan Galbraith
I think this is fine. It seems clear, and limits the number of new standard names that will be needed. Of course, if people use these without specifying the vocabulary and/or some reference to a description of the tests, they lose a lot of their meaning. My aggregate_quality_flag might

Without wanting to belabor this point, since it's clearly been decided, I'd like to point out that the DOI can in no way replace the description of CF in the Conventions attribute: 'files that follow these conventions indicate this by setting the NUG defined global attribute Conventions to the
