Hi All -
Maintaining a gazetteer seems a little outside the scope of CF -
wouldn't it be preferable to require (or at least allow) an
attribute
for the "region" variable pointing to an external vocabulary?
char geo_region(lbl,strlen) ;
geo_region:standard_name="region" ;
geo_region:vocabulary_name="GCMD Location Keywords" ;
I thought SeaDataNet might have a good candidate for this, but a
quick search on the NERC vocab server makes me think that they've
separated out sea and land area names, and that would clearly cause
problems for some types of data.
So, as far as I know, GCMD has the only (well publicized) set of
terms
that includes water bodies as well as land areas.
The GCMD list seems to have been updated this past October; it is
available
at gcmd.nasa.gov/Resources/valids/archives/keyword_list.html
Cheers - Nan

Dear Alison and all,
I have not objection to adding the region. I also favor the
Standard Names Committee (and you) be responsible for the region
names. Finally, I would ask the committee to consider adding
any CMIP5 region identifiers to the official list, unless of
course those names seem inappropriate.
thanks,
Karl

Dear Jonathan,
In September Jim Biard requested a standardized region name for the contiguous United States. Several people commented and there was general agreement that contiguous_united_states would be a suitable string to add to the list of region names.
Before I proceed, however, I note that the file on the CF website which contains the region names also contains the following introductory text:
"This list was based on the NASA GCMD keyword list for locations which was valid on 12 December 2002. We retained only the names of geographical regions from the GCMD list, changing them to lower case and replacing the separators within the names by underscores to be consistent with the style used for CF standard names. We excluded (a) countries (these could be added if required), (b) regions that could be specified by coordinate ranges in CF (e.g. western hemisphere), (c) ill-defined regions (e.g. west Africa), (d) names for layers and surfaces of the Earth (e.g. mantle, sea floor), which are or would be included in standard names if required. We have also added names shown like this. Our intention is to keep this list consistent with GCMD."
I wonder if this list has ever been updated since December 2002 (I certainly haven't made any changes). Does the list need to be reviewed? Also, strictly speaking, the region list is separate from the standard name table, so do we want it to be maintained along with standard names (I'm happy to keep it up to date if the answer is 'yes') or should it be regarded as the domain of the conventions committee? I'd appreciate it if we can clarify who should be maintaining the list before I go ahead and start making modifications. I think there may be some CMIP5 related region names that are also not currently part of the list.
Best wishes,
Alison

Subject: Re: [CF-metadata] Request for a region standard_name
Dear Jim
Following Don's comment, if you'd be happy with a standard region name
of
contiguous_united_states, and since no-one else has objected, I think
we
should agree to that. (We can omit of_america; I would expect people to
know
where the united_kingdom is without
of_great_britain_and_northern_ireland!)
I expect Alison will comment and/or add it to the table when she is
able to.
Cheers
Jonathan
