Hi all,
This is too bad that udunits is not backward compatible. I vote for CF
to recommend using the latest available udunits library.
Best regards,
Karl

Hi all,
I'm running into some problems regarding units in CF-compliant files.
Up until now I've been using udunits 1 to check units, but I recently
tried the CF checker which uses udunits2. There are some unit strings
which are valid in one but not the other. In particular, I am dealing
with milligrams per cubic meter. In udunits1, I used 'ukg m^-3', which
udunits2 rejects as invalid. udunits2 accepts 'mg m^-3' (which is much
better!), but udunits1 interprets this as to do with gravity. Because
of this, I can't include a unit string which is generally compatible
with udunits...
I would guess that udunits2 is the preferred option, given that
udunits1 is deprecated. Should the CF conventions be updated to
specify udunits 2?
Cheers,
Andrew Clegg
