Dear Jonathan,
-> 'atmosphere' synonymous to _in_air ?
The Guidelines for Construction of CF Standard Names
http://cf-pcmdi.llnl.gov/documents/cf-standard-names/guidelines
state for 'atmosphere' under 'Special Phrases':
'atmosphere: used instead of in_air for quantities which are large-scale
rather than local '
I agree with what you say, that 'atmosphere' is not synonymous to
_in_air, but not only concerning the spatial scales. For chemical names
there is another difference, and I was referring to this: atmosphere
means not-ocean, not-land, not-vergation, etc., in the Earth system, but
in the atmosphere. This includes in_air, in_clouds, in_precipitation,
etc. Hence, in_air is a sub-element of (_in)_atmosphere, at least this
is what I thought we had defined. Maybe I am wrong?
-> _atmosphere or _in_atmosphere?
I am sorry that I have not raised this issue earlier. Why are
moles_of_G treated differently? The main distinction between gases and
aerosols is that gases have a defined molar mass, whereas most aerosols
do not have.
Best regards,
Christiane

Dear Christiane
Why do you not think that there is a problem if 'atmosphere' is stated to
be synonymous to _in_air, if this is simply wrong?
I don't think they are synonymous.
And the position of _atmosphere or _in_atmopshere should be consistent to
allow for automatic generation of standard names as discussed for
aerosols and chemistry, and to avoid the each time the discussion starts
again.
It is a systematic distinction, so it could be made automatically. It is
in_atmosphere for moles_of_G, and atmosphere_ for everything else. The only
reason is that atmosphere_number_of_moles was not suggested, or did not sound
right (I can't remember), during that discussion. You may remember that was
the discussion about "burden", when we decided to say "number of moles" to
be explicit about what it meant. We could change to atmosphere_number_of_moles
for consistency (that would affect about 35 names).
Best wishes
Jonathan
