Thanks Dan,
Nicely put together and I can't see any issues.
Cheers, Roy.

Subject: [CF-metadata] New halocarbon standard name requests
Dear All,
I'd like to request an addition to the standard name list for atmospheric measurements of halocarbons dichloromethane, chloroform, perchloroethene, carbon tetrachloride, methyl chloroform and octafluoropropane. Here are the details of the proposed standard names.
Proposal for a new standard variable names:
Dichloromethane
Standard name: mole_fraction_of_dichloromethane_in_air (Canonical unit: 1)
Long name: 'Mole fraction is used in the construction mole_fraction_of_X_in_Y, where X is a material constituent of Y. A chemical or biological species denoted by X may be described by a single term such as "nitrogen" or a phrase such as "nox_expressed_as_nitrogen". The chemical formula for dichloromethane is CH2Cl2. The IUPAC name is dichloromethane.
Chloroform
Standard name: mole_fraction_of_chloroform_in_air (Canonical unit: 1)
Long name: 'Mole fraction is used in the construction mole_fraction_of_X_in_Y, where X is a material constituent of Y. A chemical or biological species denoted by X may be described by a single term such as "nitrogen" or a phrase such as "nox_expressed_as_nitrogen". The chemical formula for chloroform is CHCl3. The IUPAC name for chloroform is trichloromethane.
Perchloroethene
Standard name: mole_fraction_of_perchloroethene_in_air (Canonical unit: 1)
Long name: 'Mole fraction is used in the construction mole_fraction_of_X_in_Y, where X is a material constituent of Y. A chemical or biological species denoted by X may be described by a single term such as "nitrogen" or a phrase such as "nox_expressed_as_nitrogen". The chemical formula for perchloroethene is CCl2CCl2. The IUPAC name for perchloroethene is tetrachloroethene.
Carbon tetrachloride
Standard name: mole_fraction_of_carbon_tetrachloride_in_air (Canonical unit: 1)
Long name: 'Mole fraction is used in the construction mole_fraction_of_X_in_Y, where X is a material constituent of Y. A chemical or biological species denoted by X may be described by a single term such as "nitrogen" or a phrase such as "nox_expressed_as_nitrogen". The chemical formula for carbon tetrachloride is CCl4. The IUPAC name for carbon tetrachloride is tetrachloromethane.
Methyl chloroform
Standard name: mole_fraction_of_methyl_chloroform_in_air (Canonical unit: 1)
Long name: 'Mole fraction is used in the construction mole_fraction_of_X_in_Y, where X is a material constituent of Y. A chemical or biological species denoted by X may be described by a single term such as "nitrogen" or a phrase such as "nox_expressed_as_nitrogen". The chemical formula for methyl chloroform is CH3CCl3. The IUPAC name for methyl chloroform is 1,1,1-trichloroethane.
PFC-218
Standard name: mole_fraction_of_pfc218_in_air (Canonical unit: 1)
Long name: 'Mole fraction is used in the construction mole_fraction_of_X_in_Y, where X is a material constituent of Y. A chemical or biological species denoted by X may be described by a single term such as "nitrogen" or a phrase such as "nox_expressed_as_nitrogen". The chemical formula for pfc218 is C3F8. The IUPAC name for pfc218 is octafluoropropane.
Thanks in advance,
Dan
