Dear John,
According to the list of names attached to
http://mailman.cgd.ucar.edu/pipermail/cf-metadata/2010/003354.html, the
quantity with long name "Surface Downward Net Flux of Iron" has the
proposed standard name of
tendency_of_ocean_mole_content_of_iron_due_to_deposition_and_runoff_and_
sediment_dissolution. We could certainly change this to
tendency_of_ocean_mole_content_of_dissolved_iron_due_to_deposition_and_r
unoff_and_sediment_dissolution (i.e. add "dissolved") if necessary.
If you need both total and dissolved fluxes we could add separate
standard names to the table, but the standard name for the total flux
should then be the one that's already proposed (i.e., we would assume
"iron" to mean "total iron" = organic/inorganic dissolved Fe2+/Fe3+ and
organic/inorganic particulate Fe2+/Fe3+).
Please could you let me know how you would like to proceed, i.e. whether
we need one or two new standard names for the iron flux quantities.
Best wishes,
Alison
