I suggest to rename all standard names (rename = create the new names
and make the old names aliases to the new ones)
I am not aware of any reasonable exceptions for X.
Further I would like to suggest to add
for chloride and sodium (units and descriptions according to the
existing other standard names of this type).
(a) As stated here
the standard name mass_concentration_of_X_dry_aerosol describes the
total dry mass of all aerosol particles that contain traces of X. There
is currently no term to describe the mass concentration of particulate X.
(b) As stated here
there is no practical application or
mass_concentration_of_X_dry_aerosol. However, for the CMIP5 experiments
the standard name atmospheric_mass_content_of_X_dry_aerosol is used to
describe the mass content of particulate X (sulfate, nitrate, ammonium)
in the atmosphere. See standard_output.pdf on
http://cmip-pcmdi.llnl.gov/cmip5/output_req.html for details:
http://cmip-pcmdi.llnl.gov/cmip5/docs/standard_output.pdf . There are
probably more situation, in which mass_concentration_of_X_dry_aerosol
and atmospheric_mass_content_of_X_dry_aerosol were wrongly used. At
least I would have used it wrongly :-) .
In order to (a) have valid standard names for the mass concentration
(and mass content) of particulate X and (b) be backward compatible with
respect to the current usage of existing standard names, I suggest to
rename the old variable names (create new one + make the old ones
aliases to the new ones) instead of just creating new ones (without
