Comment (by jonathan):

 Dear Nan

 Replying to [comment:34 ngalbraith]:
 > Also, we might want to consider allowing all 4 of the existing modifiers
 to have standard names (or category names, as was suggested earlier), as
 long as they are applied to primary data variables that share units. There
 could easily be a single detection_minimum, and maybe also a single
 standard_error, for e.g. wind or current vectors.

 I don't think we can do that, because a given standard name must have
 unique canonical units. We couldn't define the canonical unit for
 detection_minimum or standard_error, since they depend on the geophysical
 quantity, as you imply.

 Best wishes

 Jonathan
