Dear all,
on Oct. 3, 2011, the following standard_names were proposed. Despite
absence of any critical comments they appear neither on the standard_name list
nor in the current proposals list:
* " mass_concentration_of_pm2p5_ambient_aerosol_in_air", units "kg m-3"
Definition: Mass concentration means mass per unit volume and is used in the
construction mass_concentration_of_X_in_Y, where X is a material constituent of
Y. A chemical species denoted by X may be described by a single term such as
'nitrogen' or a phrase such as 'nox_expressed_as_nitrogen'. "Aerosol" means the
suspended liquid or solid particles in air (except cloud droplets). "Ambient
aerosol" is aerosol that has taken up ambient water through hygroscopic growth.
The extent of hygroscopic growth depends on the relative humidity and the
composition of the aerosol. "Pm2p5 aerosol" is an air pollutant with an
aerodynamic diameter of less than or equal to 2.5 micrometers. To specify the
relative humidity and temperature at which the particle size applies, provide
scalar coordinate variables with the standard names of, respectively,
"relative_humidity" and "air_temperature".
* " mass_concentration_of_pm1_ambient_aerosol_in_air", units "kg m-3"
Definition: Mass concentration means mass per unit volume and is used in the
construction mass_concentration_of_X_in_Y, where X is a material constituent of
Y. A chemical species denoted by X may be described by a single term such as
'nitrogen' or a phrase such as 'nox_expressed_as_nitrogen'. "Aerosol" means the
suspended liquid or solid particles in air (except cloud droplets). "Ambient
aerosol" is aerosol that has taken up ambient water through hygroscopic growth.
The extent of hygroscopic growth depends on the relative humidity and the
composition of the aerosol. "Pm1 aerosol" is an air pollutant with an
aerodynamic diameter of less than or equal to 1 micrometer. To specify the
relative humidity and temperature at which the particle size applies, provide
scalar coordinate variables with the standard names of, respectively,
"relative_humidity" and "air_temperature". [Note that pm1 actually coincides
with the current definition of "coarse_mode" - it may be helpful to allow b
oth terms as aliases]
* " mass_concentration_of_pm10_ambient_aerosol_in_air", units "kg m-3"
Definition: Mass concentration means mass per unit volume and is used in the
construction mass_concentration_of_X_in_Y, where X is a material constituent of
Y. A chemical species denoted by X may be described by a single term such as
'nitrogen' or a phrase such as 'nox_expressed_as_nitrogen'. "Aerosol" means the
suspended liquid or solid particles in air (except cloud droplets). "Ambient
aerosol" is aerosol that has taken up ambient water through hygroscopic growth.
The extent of hygroscopic growth depends on the relative humidity and the
composition of the aerosol. "Pm10 aerosol" is an air pollutant with an
aerodynamic diameter of less than or equal to 10 micrometers. To specify the
relative humidity and temperature at which the particle size applies, provide
scalar coordinate variables with the standard names of, respectively,
"relative_humidity" and "air_temperature".

[PJC] After a quick read these all look good to me :-).
I request addition to the standard_name table within 1 month.
