Dear All, No comments have been received regarding the names proposed for DAMIP. I think the names, units and definitions are fine, so I am now accepting all these names for publication in the standard name table. They will be added in the June update.

CMIP6 short name jo2. photolysis_rate_of_molecular_oxygen (s-1) ' "Photolysis" is a chemical reaction in which a chemical compound is broken down by photons. The "reaction rate" is the rate at which the reactants of a chemical reaction form the products. The chemical formula for molecular oxygen is O2.' 2. CMIP6 short name jo3. photolysis_rate_of_ozone (s-1) ' "Photolysis" is a chemical reaction in which a chemical compound is broken down by photons. The "reaction rate" is the rate at which the reactants of a chemical reaction form the products. The chemical formula for ozone is O3. The IUPAC name for ozone is trioxygen. The quantity with standard name photolysis_rate_of_ozone is the rate of photolytic loss of ozone, including all possible photolysis channels to form ground state atomic oxygen (O3P ) and excited (singlet D) atomic oxygen (O1D). Photolysis to the excited state only has the standard name photolysis_rate_of_ozone_to_1D_oxygen_atom.' 3. CMIP6 short name oxloss. tendency_of_mole_concentration_of_ox_in_air_due_to_chemical_destruction (mol m-3 s-1) 'The phrase "tendency_of_X" means derivative of X with respect to time. Mole concentration means number of moles per unit volume, also called "molarity", and is used in the construction "mole_concentration_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 term "ox" means a combination of three radical species containing 1 or 3 oxygen atoms: O + O1d + O3. The specification of a physical process by the phrase "due_to_" process means that the quantity named is a single term in a sum of terms which together compose the general quantity named by omitting the phrase. "Chemical destruction" means the result of all chemical reactions within the medium (here, atmosphere) that remove a certain amount of a particular species from the medium.' 4. CMIP6 short name oxprod. tendency_of_mole_concentration_of_ox_in_air_due_to_chemical_and_photolytic_production (mol m-3 s-1) 'The phrase "tendency_of_X" means derivative of X with respect to time. Mole concentration means number of moles per unit volume, also called "molarity", and is used in the construction "mole_concentration_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 term "ox" means a combination of three radical species containing 1 or 3 oxygen atoms: O + O1d + O3. The specification of a physical process by the phrase "due_to_" process means that the quantity named is a single term in a sum of terms which together compose the general quantity named by omitting the phrase. The phrase "chemical and photolytic production" means the result of all chemical and photolytic reactions within the medium (here, atmosphere) that produce a certain amount of the particular species.' 5. CMIP6 short name vmrox. mole_fraction_of_ox_in_air (1) 'Mole fraction is used in the construction "mole_fraction_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". The term "ox" means a combination of three radical species containing 1 or 3 oxygen atoms: O + O1d + O3.' In addition, Martin has suggested we modify the definition of the existing name photolysis_rate_of_ozone_to_1D_oxygen_atom (s-1) to provide a cross-reference to the new name proposed in (1). ' "Photolysis" is a chemical reaction in which a chemical compound is broken down by photons. The "reaction rate" is the rate at which the reactants of a chemical reaction form the products. The chemical formula for ozone is O3. The IUPAC name for ozone is trioxygen. "1D oxygen atom" means the singlet D state, an excited state, of the oxygen atom. The combined photolysis rate of ozone to both excited and ground state oxygen atoms has the standard name photolysis_rate_of_ozone.' My own feeling is that these proposals all look okay, but any questions or comments to improve the names would be welcome.
