Just a brief reminder.

Dear CF-Mailinglist,
I suggest to rename all standard names (rename = create the new names
and make the old names aliases to the new ones)
atmospheric_mass_content_of_X_dry_aerosol
to
atmospheric_mass_content_of_X_in_dry_aerosol
and
mass_concentration_of_X_dry_aerosol_in_air
to
mass_concentration_of_X_in_dry_aerosol_in_air
and
atmosphere_mass_content_of_sulfate_dry_aerosol_particles_expressed_as_sulfur
to
atmosphere_mass_content_of_sulfate_in_dry_aerosol_particles_expressed_as_sulfur
I am not aware of any reasonable exceptions for X.
Further I would like to suggest to add
atmospheric_mass_content_of_X_in_dry_aerosol
mass_concentration_of_X_in_dry_aerosol_in_air
for chloride and sodium (units and descriptions according to the
existing other standard names of this type).
Reasons:
(a) As stated here
(http://mailman.cgd.ucar.edu/pipermail/cf-metadata/2017/059588.html)
and here
(http://mailman.cgd.ucar.edu/pipermail/cf-metadata/2017/059554.html),
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
(http://mailman.cgd.ucar.edu/pipermail/cf-metadata/2017/059588.html)
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 alias-ing).
Regards,
Daniel
