[CF-metadata] request for standard name

Maybe instead of ' radar_quality_index' NCEI could use a more general
approach; an ancillary variable of radar_qc, and then a standard attribute
that describes how the  QC variable is calculated.

As far as I know there's no way, currently,  to provide such a 
description in
a way that would be clear to data users, but this approach would avoid a
proliferation of quality_index standard names.

I don't know about different radar systems, but a very similar concept 
could be
applied to ADCP data, perhaps by combining echo amplitude and percent good
to get a more 'complete' QC variable. We don't routinely do that, but it 
might be
useful, if we had a standard way to document the meaning of the 
resulting QC
value and the way it was calculated.

Cheers - Nan
