Hello all -

It's been a long time, but is anyone interested in re-visiting the subject
of units for practical salinity in CF?

I was recently notified that my salinity data was likely to be 
overlooked by
some users, because I'd used '1' as the units, not '.001'. Somehow, I'd
forgotten the (long-ago) discussion on the CF list about salinity units.

Some members of  the OceanSITES project are interested in revising our
format spec to encourage the use of '1' as an indication that salinity does
not have units - but, of course, we'd mostly rather remain CF-compliant.

Thanks for any feedback on this.

Cheers - Nan
