Dear Christiane and Jonathan ...,
I overworked my proposal and tried to answer your question with Luca's help.
I have changed the position of 'expressed as' without comments. It
should belong
to the species. Does everyone agree?
atmosphere_number_content_of_X (new physical parameter)
******************************
atmosphere_number_content_of_cloud_droplet
atmosphere_number_content_of_ice_crystal
atmosphere_number_content_of_aerosol_particle
This was Jonathan's proposal.
Christiane talked about _in_air. But I think that does not fit.
For example _in_cloud is not in_air. Is that right, Christiane?
I would eliminate the medium 'atmosphere_' in the standard name,
but I know this is not the status quo. See my answer to Karl's proposal.

We agree.

***************************************
Christiane proposed:
I would summarize the impact under turbulent and just say
_turbulent_depostion, because it applies to particles moving in
turbulent flow.
We agree.
Christiane agreed:
turbulent_dep. + sedimentation = dry_dep

Christiane said this is equal to:

We agree.
tendency_of_atmosphere_mass_content_of_dry_aerosol_sulfur_expressed_as_sulfur_due_to_emission
(This is the total emission of Sulfur species (SO2+SO4+DMS) expressed in
kg(S))
Christiane asked:
tendency_of_atmosphere_mass_content_of_sulfur_dry_aerosol_expressed_as_sulfur_due_to_emission
and can also be H2S and COS?
Yes, HAMMOZ does not have H2S and COS. So in our case sulfur emissions
are only sum of
SO2(gas),H2SO4(gas),SO4(aerosol),DMS(gas)

Christiane said: This should be:
tendency_of_atmosphere_mass_content_of_sulfur_dry_aerosol_expressed_as_sulfur_due_to_wet_deposition
(sulfate=sulfur?)
We would say sulfate, because it is deposition of sulfate aerosol and
not other sulfuric species.
Christiane why do you think 'sulfur' is better. You probably have good
reasons for this?

Christiane asked:
I do not understand the sense of these names? why layer?
atSurfaceLayer??
atSurfaceLayer was a comment. Sorry for that.
Why do you change the unit from kg to ug?
We changed the units to micrograms/m3 because these fields are hourly
averaged values of PM and PM
components which will be tipically compared to measurements which are
normally expressed in micrograms/m3.
In the same dataset there is anyway the variable rhoam1, which is air
denisty [kg/m3] which can be
used to convert back aerosol concentration to mass mixing ration
[kg/kg]. If micrograms is not accepted
we can use kg/m3, but we should correct the variables in the data set.
I would like to discuss micrograms. I was not able to find it in
http://www.unidata.ucar.edu/software/udunits/udunits-1/udunits.txt ?
Is it in udunits-2. Is a link available? If micrograms is part of it we
can use kg for the standard name list. If not
we should discuss this.

Christiane said:
I do not think that _total_ is needed, as it is not used in other names that
are the sum of different components.
We agree.
rad the units are dimensionless

Christiane said:
There is not exact definition for Aitken, Coarse mode particles, hence I
would suggest to avoid these names in CF.
We agree that there isn't clear definition for these aerosol classes.
Alternative
could be to give the exact distribution properties in the CF name, for
example coarse
mode can be described as particles with number median radius greater
than 0.5 micrometers.
Could we use a scalar coordinate variable for the radius?

Christiane asked:
Why aerosol_particle and not _aerosol_ ?
What is a wet/dry_aerosol_particle_ambient_aerosol?
Luca answered:
Yes, now I realize we used _particle_ only for this group of variables.
We can omit 'particle'.
Also, wet/dry distinguish between soluble and insoluble particles which
can uptake or not ambient
water. So the definition wet_aerosol_ambient is maybe redundant, as
ambient aerosol means aerosol
that has taken up ambient water through hygroscopic growth.
