Actually, the CF Conventions don't standardize any dimension or variable names, according to the beginning of section 1.3: No variable or dimension names are standardized by this convention. Instead we follow the lead of the NUG [NetCDF Users Guide] and standardize only the names of attributes and some of the values taken by those attributes. So "standard_name" attributes for the associated coordinate variables may be what we need. This also has the advantage of permitting multiple line and sample dimensions and multiple associated coordinate variables in the same file, for multiple instruments or resolutions. The process for getting standard names approved is simpler and faster than writing CF Trac proposals for inclusion in the CF Conventions text. Although "line" and "sample" would be fine for dimension and coordinate variable names, I think they would be too generic for standard names, which have to be very descriptive. Does anyone else familiar with the CF idioms and customs for standard names for coordinate variables and have more descriptive suggestions? --Russ > -- > Jim Biard > > Government Contractor, STG Inc. > Remote Sensing and Applications Division (RSAD) > National Climatic Data Center > 151 Patton Ave. > Asheville, NC 28801-5001 > > jim.biard@xxxxxxxx > 828-271-4900 > > _______________________________________________ > cf-satellite mailing list > cf-satellite@xxxxxxxxxxxxxxxx > For list information or to unsubscribe, visit: http://www.unidata.ucar.edu/ma > iling_lists/
