Dear Roy,
1. Would a typical atmospheric physicist searching for sound velocity
in air data be happy to receive hits from data sets containing air
density, but not sound velocity per se?
I don't think so. As I recall the speed of sound in a gas is
approximately proportional to the square
Andreas,
Your quantity is a specific instance of the generic quantity
"amount-of-substance concentration" (SI unit: "mol/m^3"). Thus, reasonable
names for it according to http://physics.nist.gov/Pubs/SP811/sec08.html would
be "amount-of-air concentration", "air-molecules concentration", or
"molecu

I agree with Alison that height is the word we use in standard names for
the vertical distance above the surface. So I think the standard_name you
need is j
Dear all,
I like the term "number_concentration_of_molecules_in_air" (m-3). Thanks,
Alison!
Best regards,

please may I obtain confirmation that this change is now amenable and will be
included in the next release of the standard names vocabulary?
Explicitly:
I would like to formally propose that the description text for standard names:
low_type_cloud_area_fraction
medium_type_cloud_area_fraction
Dear Alison,
thanks for your quick reply! I'll go with your suggestion of
height_of_atmosphere_layer_above_surface (m)
and use this as long_name attribute (as I'm using Iris which is very
strict and doesn't accept standard_names which are not in the official
standard name table).
Cheers,
Dear Andreas,
In CF, "height" is defined with reference to the earth's surface: "Height is
the vertical distance above the surface." ("Altitude" is defined as "the
(geometric) height above the geoid, which is the reference geopotential
surface. The geoid is similar to mean sea level.")
Hence
Dear Andreas,
This might sound like a silly question, but what do you mean by "air"? Do you
mean just the mixture of gases or do you mean everything that might
be found in a random sample of air, including aerosol particles and
precipitation?
If you mean strictly the gases, then I would sugges
Hi guys,
I have another question: How would I express "altitude (of atmosphere
layer) above surface" in terms of CF standard names?
Thanks,

Hi guys,
I'm wondering how to express the air number density, i.e., the number of
air molecules per unit volumne (in mole cm-3), in terms of CF standard
names?

Dear All,
Two simple questions that have arisen from the need for atmospheric physics
data discovery in SeaDataNet.
1) Would a typical atmospheric physicist searching for sound velocity in
