JGregory: UDUNITS used for CF

It doesn't matter to CF what units are used, so long as they are udunits. Any dimensionally equivalent unit can be used for a given standard name. --JonathanGregory 16:51, 22 May 2006 (EDT)


___RHusar: Units page added to Wiki

This is a good reminder that in addition to updating the CF standard names, we also have to check to make sure that the list of units in UDUNITS includes the units used to measure chemical/aerosol entities. We should make another wiki page specifically to deal with the units. In fact, that units page has been added (a placeholder). This page is the discussion attached to the units page. An additional section for units has been added in the main page.--Rhusar 19:27, 22 May 2006 (EDT)

JGregory: Don't mix units with the Compound

However, kgC and kgS aren't SI units. I think the unit has to be kg. This implies that it's the standard name which must somehow indicate that it is the mass of C or mass of S which is being referred to, rather than the mass of the compound e.g. dry_deposition_flux_of_sulfur_as_sulfate_at_surface. --JonathanGregory 16:51, 22 May 2006 (EDT)


JGregory: Mole Fraction or Mass Fraction

You may indeed prefer mole_fraction for some quantities and mass_fraction for others. That would be your own decision for your project, but of course another project might make a different choice. --JonathanGregory 16:51, 22 May 2006 (EDT)
