Hello Mike
there is a ticket open on the TRAC system proposing the use of OGC WKT to describe coordinate reference systems:

Would this give you the vocabulary you require?

Subject: [CF-metadata] Proposed new standard name: projection_zone
This has a corresponding new grid_mapping_name attribute value: universal_transverse_mercator
This was last discussed in depth in 2005, and I believe the resolution was that the attributes corresponding to the "transverse_mercator" mapping were perfectly adequate to describe the projection within any given zone.
However, I am trying to represent the trajectory of a vehicle that typically crosses zones, and there does not seem to be a satisfactory means for documenting a multi-zone trajectory with the current attribute set. Granted, specifying only the UTM zone is much less descriptive than the full set of transverse mercator mappring attributes, but UTM really is pretty well universally understood, and I'd be surprised to find a mapping library that can't handle a UTM zone integer as the full description of the mapping.
Hence, I propose:
standard_name: projection_zone, units: 1
Best, Mike
