Re: [CF-metadata] Usage of the 'Conventions' attribute

2013-01-29 Thread Bentley, Philip
Hi Nan, I agree with Roy that CF should be the default namespace in a CF compliant file... What does that mean? Until we agree on the meaning and mechanism of namespace-handling within CF-compliant files and software, I fear that such statements do not provide much guidance at the

2013-01-28 Thread Bentley, Philip
Roy et al., Martin's comments on namespace highlight a concern I identified whilst doing the research for the SeaDataNet specification. Several communities have added large numbers of both global and variable attributes with no indication of namespace. Not only does this make it

2012-02-29 Thread Bentley, Philip
Hi Stephen, I may well be wrong, but I suspect that one of the reasons - perhaps the main reason - why folks would like access to a stand-alone cfchecker utility is the large size of their netcdf files. (It's certainly the reason we use a local version.) As you know only too well (from CMIP5),

Hi Stephane, Would one or both of the following two standard names cover your use-case? The first is in effect your residual, I think. -- standard name: water_surface_height_above_reference_datum canon units: m description: 'Water surface height above reference datum' means

[CF-metadata] CF Ticket #69: Specification of Coordinate Reference System properties in Well-Known Text format

2011-10-10 Thread Bentley, Philip
Hi folks, FYI, I have posted to the CF Trac site a technical proposal regarding the suggested use of the well-known text format to encode additional coordinate system properties in CF-netCDF files. You can find the proposal at the following URL: https://cf-pcmdi.llnl.gov/trac/ticket/69

Hi all, Polite request: can folks not attach names - well, at least not mine! - to message subject lines. Although it may temporarily boost one's google rating :-) it can also give the impression that the named person endorses the views and opinions expressed in the message. Which may or may not

Hi Ethan, All good questions! I've provided some brief - and probably inadequate - responses inline. I've been working up an initial (reasonably concise) proposal covering this topic, which potentially I could upload to the CF trac site later this week. I guess it depends on whether folks would

Hi Ros, This has prompted me to mention a CF compliance issue that I spotted last week in connection with the netCDF files we're producing for the CMIP5 project using the latest CMOR-2 library. When I validated one of these files against the latest online version of the CF-checker utility

Hi Roy, Would simply inventing an artificial new term to represent sea+lakes+rivers be an option here? Presumably, back in the day, there was no word for a land-locked body of fresh water so someone thought, I know, I'll call it a 'lake'. Or whatever the latin/greek equivalent was back then! So
