Dear all,
I would like to propose a set of new standard names for atmospheric sea
salt concentrations and for nitrogen deposition. I suggested them
already in March - this is some kind of a reminder.
The suggested names are numbered and the reasons for suggesting these
names are given below the list. The full descriptions are attached in
the end of this e-mail.
suggested name, unit:
( 1) mass_concentration_of_pm10_seasalt_dry_aerosol_particles_in_air,
kg m-3
( 2)
mass_concentration_of_pm2p5_seasalt_cation_dry_aerosol_particles_in_air,

( 6) atmosphere_mass_content_of_seasalt_cation_dry_aerosol_particles,
( 7) mass_fraction_of_seasalt_cation_dry_aerosol_particles_in_air, 1
( 8)

kg m-3
( 9)
mass_concentration_of_pm2p5_seasalt_cation_dry_aerosol_particles_in_air,
kg m-3
(10) mass_concentration_of_chloride_dry_aerosol_particles_in_air, kg m-3
(11) mass_fraction_of_chloride_dry_aerosol_particles_in_air, 1
(12) mole_concentration_of_chloride_in_air, mol m-3
(13)

kg m-2 s-1
(15)

kg m-2 s-1
(16)

kg m-2 s-1
(17)
tendency_of_atmosphere_mass_content_of_oxidized_nitrogen_due_to_wet_deposition,
kg m-2 s-1
(18)
tendency_of_atmosphere_mass_content_of_reduced_nitrogen_due_to_wet_deposition,
kg m-2 s-1
(19)

(20)
tendency_of_ocean_mole_content_of_oxidized_nitrogen_due_to_deposition,
mol m-2 s-1
(21)
tendency_of_ocean_mole_content_of_reduced_nitrogen_due_to_dry_deposition,
mol m-2 s-1
(22)
tendency_of_ocean_mole_content_of_oxidized_nitrogen_due_to_dry_deposition,
mol m-2 s-1
(23)
tendency_of_ocean_mole_content_of_reduced_nitrogen_due_to_wet_deposition,
mol m-2 s-1
(24)
tendency_of_ocean_mole_content_of_oxidized_nitrogen_due_to_wet_deposition,
mol m-2 s-1
Reason for (1) and (2): These standard names exist already as
"mass_fraction" but not as "mass_concentration". However, the total mass
(which we need to calculate the mass fraction) is not always known.
Therefore, the mass_fraction might not be applicable in some situations.
Reason for (3) to (9): The mass of "seasalt_dry_aerosol_particles" is
ambiguous. Providing the mass of "seasalt_cation_dry_aerosol_particles"
is less ambiguous. At the time of emission, sea salt particles consist
of Chloride, Sulfate, Sodium, and further cations with mass fractions
each below 4%. When the sea salt ages and acids as nitric and sulfuric
acid condense/form on the wet sea salt particles, chloride exporates as
HCl (hydrochloric acid). Thus, the mass of the original sea salt ions
decreases during aging. In the past, some chemistry transport models
considered sea salt particles as one bulk species, which is no affected
by this chloride displacement. Maybe some models still consider it as
one. When sea salt is measured, commonly sodium and sometimes magnesium
are considered as sea salt tracers, from which the original sea salt
concentration is calculated. The same states for several modern
chemistry transport models with speciated sea salt. Because atmospheric
sea salt concentrations are commonly calculated on the base of cations
(mainly sodium) and because these concentrations do not decrease, it
might be better provide sea salt cation data instead of total sea salt
data. It should be noted in a comment which species (which cations) are
included and which mass ratios they have (see my suggestion for the
description).
Reasons for (10) to (12): Currently, standard names only exist for some
[cation]-chloride ion-compounds but not for chloride individually. When
considering aged sea salt it might be intesting to have the chloride
concentrations available.
Reason for (13) to (18): For marine ecosystem modelling, reduced and
oxizied nitrogen compounds need to be distinguished. Atmospheric
deposition is one source for marine nitrogen compounds.
Reason for (19) to (24): Consistency. New names (13) to (18) are for the
output files of chemistry transport models, whereas (19) to (24) are for
input files of marine biogeochemical models.

Daniel
