Dear All, looking at the discussion in this thread in conjunction with that in the ECHAM5-hammoz thread there are a number of main points arising:
1) In this discussion agreement has been reached to change all names following the pattern of: [tendency_of_]moles_of_X_in_atmosphere|troposphere|middle_atmosphere to [tendency_of_]atmosphere|troposphere|middle_atmosphere_moles_of_X where X is the name of a chemical species. Therefore, the following aliases will be created in the standard name table: moles_of_carbon_monoxide_in_atmosphere becomes atmosphere_moles_of_carbon_monoxide moles_of_carbon_tetrachloride_in_atmosphere becomes atmosphere_moles_of_carbon_tetrachloride moles_of_cfc11_in_atmosphere becomes atmosphere_moles_of_cfc11 moles_of_cfc113_in_atmosphere becomes atmosphere_moles_of_cfc113 moles_of_cfc114_in_atmosphere becomes atmosphere_moles_of_cfc114 moles_of_cfc115_in_atmosphere becomes atmosphere_moles_of_cfc115 moles_of_cfc12_in_atmosphere becomes atmosphere_moles_of_cfc12 moles_of_halon1202_in_atmosphere becomes atmosphere_moles_of_halon1202 moles_of_halon1211_in_atmosphere becomes atmosphere_moles_of_halon1211 moles_of_halon1301_in_atmosphere becomes atmosphere_moles_of_halon1301 moles_of_halon2402_in_atmosphere becomes atmosphere_moles_of_halon2402 moles_of_hcc140a_in_atmosphere becomes atmosphere_moles_of_hcc140a moles_of_hcfc22_in_atmosphere becomes atmosphere_moles_of_hcfc22 moles_of_methane_in_atmosphere becomes atmosphere_moles_of_methane moles_of_methyl_bromide_in_atmosphere becomes atmosphere_moles_of_methyl_bromide moles_of_methyl_chloride_in_atmosphere becomes atmosphere_moles_of_methyl_chloride moles_of_molecular_hydrogen_in_atmosphere becomes atmosphere_moles_of_molecular_hydrogen moles_of_nitrous_oxide_in_atmosphere becomes atmosphere_moles_of_nitrous_oxide tendency_of_moles_of_carbon_monoxide_in_atmosphere becomes tendency_of_atmosphere_moles_of_carbon_monoxide tendency_of_moles_of_carbon_monoxide_in_middle_atmosphere becomes tendency_of_middle_atmosphere_moles_of_carbon_monoxide tendency_of_moles_of_carbon_monoxide_in_troposphere becomes tendency_of_troposphere_moles_of_carbon_monoxide tendency_of_moles_of_carbon_tetrachloride_in_atmosphere becomes tendency_of_atmosphere_moles_of_carbon_tetrachloride tendency_of_moles_of_cfc11_in_atmosphere becomes tendency_of_atmosphere_moles_of_cfc11 tendency_of_moles_of_cfc113_in_atmosphere becomes tendency_of_atmosphere_moles_of_cfc113 tendency_of_moles_of_cfc114_in_atmosphere becomes tendency_of_atmosphere_moles_of_cfc114 tendency_of_moles_of_cfc115_in_atmosphere becomes tendency_of_atmosphere_moles_of_cfc115 tendency_of_moles_of_cfc12_in_atmosphere becomes tendency_of_atmosphere_moles_of_cfc12 tendency_of_moles_of_halon1202_in_atmosphere becomes tendency_of_atmosphere_moles_of_halon1202 tendency_of_moles_of_halon1211_in_atmosphere becomes tendency_of_atmosphere_moles_of_halon1211 tendency_of_moles_of_halon1301_in_atmosphere becomes tendency_of_atmosphere_moles_of_halon1301 tendency_of_moles_of_halon2402_in_atmosphere becomes tendency_of_atmosphere_moles_of_halon2402 tendency_of_moles_of_hcc140a_in_atmosphere becomes tendency_of_atmosphere_moles_of_hcc140a tendency_of_moles_of_hcc140a_in_middle_atmosphere becomes tendency_of_middle_atmosphere_moles_of_hcc140a tendency_of_moles_of_hcc140a_in_troposphere becomes tendency_of_troposphere_moles_of_hcc140a tendency_of_moles_of_hcfc22_in_atmosphere becomes tendency_of_atmosphere_moles_of_hcfc22 tendency_of_moles_of_hcfc22_in_troposphere becomes tendency_of_troposphere_moles_of_hcfc22 tendency_of_moles_of_methane_in_atmosphere becomes tendency_of_atmosphere_moles_of_methane tendency_of_moles_of_methane_in_middle_atmosphere becomes tendency_of_middle_atmosphere_moles_of_methane tendency_of_moles_of_methane_in_troposphere becomes tendency_of_troposphere_moles_of_methane tendency_of_moles_of_methyl_bromide_in_atmosphere becomes tendency_of_atmosphere_moles_of_methyl_bromide tendency_of_moles_of_methyl_bromide_in_middle_atmosphere becomes tendency_of_middle_atmosphere_moles_of_methyl_bromide tendency_of_moles_of_methyl_bromide_in_troposphere becomes tendency_of_troposphere_moles_of_methyl_bromide tendency_of_moles_of_methyl_chloride_in_atmosphere becomes tendency_of_atmosphere_moles_of_methyl_chloride tendency_of_moles_of_methyl_chloride_in_middle_atmosphere becomes tendency_of_middle_atmosphere_moles_of_methyl_chloride tendency_of_moles_of_methyl_chloride_in_troposphere becomes tendency_of_troposphere_moles_of_methyl_chloride tendency_of_moles_of_molecular_hydrogen_in_atmosphere becomes tendency_of_atmosphere_moles_of_molecular_hydrogen tendency_of_moles_of_molecular_hydrogen_in_middle_atmosphere becomes tendency_of_middle_atmosphere_moles_of_molecular_hydrogen tendency_of_moles_of_molecular_hydrogen_in_troposphere becomes tendency_of_troposphere_moles_of_molecular_hydrogen tendency_of_moles_of_nitrous_oxide_in_atmosphere becomes tendency_of_atmosphere_moles_of_nitrous_oxide 2) Agreement has been reached that new 'local media' of in_cloud_water, in_cloud_liquid_water and in_cloud_ice will be useful for describing dissolved chemical species. I will add these to the list of acceptable values in the 'Medium' section of the standard name guidelines. 3) Position of large-scale and local medium within the standard name. Following on from the discussion of large-scale and local media (e.g. 'atmosphere' versus 'in_air') and their respective positions within the standard name, Christiane has suggested that large-scale medium should always appear as a prefix and local medium as a postfix. This is consistent with existing atmosphere/ocean and in_air/in_sea_water standard names (including the moles_of_X names when the change in (1) is implemented). I propose therefore to amend the standard name guidelines as follows a) In the 'Qualifications' section, change the pattern for constructing standard names from [surface] [component] standard_name [at surface] [in medium] [due to process] [assuming condition] to [surface] [component] [large-scale medium] standard_name [at surface] [in local medium] [due to process] [assuming condition] b) Add a new section entitled 'Large-scale medium' following the existing 'Component' section: Large-scale medium The medium throughout which a quantity applies: atmosphere, troposphere, stratosphere, mesosphere, thermosphere, middle_atmosphere, ocean. c) Alter the title of the existing 'Medium' section to 'Local Medium' and alter the wording as follows: Local medium The local medium or layer within which an intensive quantity applies: in_air, in_atmosphere_boundary_layer, in_sea_ice, in_sea_water, in_soil, in_soil_water, in_cloud_water, in_cloud_liquid_water, in_cloud_ice. I would welcome any comments on the proposed changes. 4) Deprecate the use of 'atmosphere_layer' in standard names in favour of using simply 'atmosphere' with a vertical coordinate and bounds variable to indicate the extent of the layer. This point was raised under the ECHAM5/Hammoz discussion. N.B. This would not affect existing soil_layer, snow_layer and atmosphere_boundary_layer names, all of which are intended to indicate a physically distinct layer in its entirety, rather than a sub-division of a larger medium. Both Jonathan and Christiane seem to be in favour of the proposal to deprecate atmosphere_layer. It would affect 31 atmosphere names and, by extension, 4 ocean_layer names. As it affects more than just atmospheric chemistry names I think this proposal should be discussed more widely before a final decision is taken. 5) There is another general point worth mentioning here that arose (in a telephone conversation) from the discussion of the CMIP5 ocean names proposed by Stephen Griffies. Stephen has questioned whether some of the existing standard names that employ the term 'ocean' should in fact use 'sea_water'. I promised to raise this again as a discussion on the mailing list in April. It seems that there is a need to review whether all names using the terms 'ocean', 'atmosphere', 'in_sea_water', 'in_air', 'atmosphere_layer' and 'ocean_layer' are doing so in a consistent manner and whether the advice in the Guidelines regarding the use of all these terms is clear. I will raise points (4) and (5) again in a general discussion of 'medium', rather than continuing under this atmosphere only thread.
