Hi,

I found the "u" micro prefix abbreviation in the current CF-1.4
documentation on units:
http://cf-pcmdi.llnl.gov/documents/cf-conventions/1.4/cf-conventions.html#units

but it seems this prefix is not available in the last udunits-2
(udunits-1 is now deprecated)

and in udunits-2 they break backward compatibility because the "u"
symbol is now used for a new unit "unified_atomic_mass_unit", see in
http://www.unidata.ucar.edu/software/udunits/udunits-2/udunits2-accepted.xml
http://www.unidata.ucar.edu/software/udunits/udunits-2/udunits2-prefixes.xml

So what is the position of the CF community concerning this point, is
the "u" micro prefix CF-1.4 compliant or not?


Thanks in advance,

Julien
