I'm likewise happy with either. I was shortly going to request names for downward_mass_flux_of_particulate_matter_in_sea_water downward_mass_flux_of_particulate_carbon_in_sea_water downward_mass_flux_of_particulate_nitrogen_in_sea_water downward_mass_flux_of_particulate_phosphorus_in_sea_water
which are pretty much the same things as Matthias is proposing, aside from the downward/sinking distinction. I looked for downward_ and sinking_ fluxes, and found 3 downward_mass_flux (but no sinking_mass_flux) 7 sinking_mole_flux (but no downward_mole_flux) It's a little goofy, but one could use downward for masses and sinking for moles.... john On Oct 10, 2013, at 14:40, Matthias Lankhorst <mlankho...@ucsd.edu> wrote: > Hi everyone, > > John is making a good point: there are multiple CF standard_names already > that > go like "downward_..._flux_...", in contrast to the "sinking_..._flux_..." > ones that I found. > > Should we eliminate one? > > I have no preference and ask everybody who does to chime in. > > I can see the benefits of having just one of the two wordings, but do not > really care which one. > > Matthias > > >> Date: Wed, 9 Oct 2013 17:17:21 -0700 >> From: John Graybeal <john.grayb...@marinexplore.com> >> To: CF Metadata List <cf-metadata@cgd.ucar.edu>, OceanSITES Data >> Management Team <oceansites-...@jcommops.org> >> Subject: Re: [CF-metadata] standard names for sediment trap data >> Message-ID: <13cc17ba-92e2-4181-beae-df80080f3...@marinexplore.com> >> Content-Type: text/plain; charset=us-ascii >> >> Hi Matthias!
