Dear All, Tim Nightingale has drawn my attention to the fact that we have two standard names in the table that appear to have identical meanings: atmosphere_water_vapor_content and atmosphere_mass_content_of_water_vapor (both kg m-2). One of these names should be made the alias of the other.
atmosphere_water_vapor_content is the older name, dating back at least to version 1 of the table, while atmosphere_mass_content_of_water_vapor first appeared in version 12 of the table, dated July 2009. The question is which name should be chosen as the current version and which one made into an alias? There are nine other existing names that use the phrase atmosphere_water_vapor_content so my initial reaction was to keep the original version of the name and make atmosphere_mass_content_of_water_vapor its alias. This would keep the consistent wording of the existing water vapor content names and require the creation of only one alias. However, a closer look at the standard name table reveals that we have 234 atmosphere_mass_content and tendency_of_atmosphere_mass_content names which have been introduced over the last couple of years for the atmospheric chemistry community. I don't think we should have two syntaxes for atmosphere mass content quantities, so I am now proposing that we should bring the following existing names in line with the chemistry names: atmosphere_cloud_condensed_water_content -> atmosphere_mass_content_of_cloud_condensed_water atmosphere_cloud_ice_content -> atmosphere_mass_content_of_cloud_ice atmosphere_cloud_liquid_water_content -> atmosphere_mass_content_of_cloud_liquid_water atmosphere_convective_cloud_condensed_water_content -> atmosphere_mass_content_of_convective_cloud_condensed_water atmosphere_convective_cloud_liquid_water_content -> atmosphere_mass_content_of_convective_cloud_liquid_water atmosphere_sulfate_content -> atmosphere_mass_content_of_sulfate atmosphere_water_content -> atmosphere_mass_content_of_water atmosphere_water_vapor_content -> atmosphere_mass_content_of_water_vapor change_over_time_in_atmosphere_water_content_due_to_advection -> change_over_time_in_atmosphere_mass_content_of_water_due_to_advection cloud_condensed_water_content_of_atmosphere_layer -> mass_content_of_cloud_condensed_water_in_atmosphere_layer cloud_ice_content_of_atmosphere_layer -> mass_content_of_cloud_ice_in_atmosphere_layer cloud_liquid_water_content_of_atmosphere_layer -> mass_content_of_cloud_liquid_water_in_atmosphere_layer lwe_thickness_of_atmosphere_water_vapor_content -> lwe_thickness_of_atmosphere_mass_content_of_water_vapor tendency_of_atmosphere_water_content_due_to_advection -> tendency_of_atmosphere_mass_content_of_water_due_to_advection tendency_of_atmosphere_water_vapor_content -> tendency_of_atmosphere_mass_content_of_water tendency_of_atmosphere_water_vapor_content_due_to_advection -> tendency_of_atmosphere_mass_content_of_water_vapor_due_to_advection tendency_of_atmosphere_water_vapor_content_due_to_convection -> tendency_of_atmosphere_mass_content_of_water_vapor_due_to_convection tendency_of_atmosphere_water_vapor_content_due_to_deep_convection -> tendency_of_atmosphere_mass_content_of_water_vapor_due_to_deep_convectio n tendency_of_atmosphere_water_vapor_content_due_to_shallow_convection -> tendency_of_atmosphere_mass_content_of_water_vapor_due_to_shallow_convec tion tendency_of_atmosphere_water_vapor_content_due_to_turbulence -> tendency_of_atmosphere_mass_content_of_water_vapor_due_to_turbulence tendency_of_water_vapor_content_of_atmosphere_layer -> tendency_of_mass_content_of_water_vapor_in_atmosphere_layer tendency_of_water_vapor_content_of_atmosphere_layer_due_to_convection -> tendency_of_mass_content_of_water_vapor_in_atmosphere_layer_due_to_conve ction tendency_of_water_vapor_content_of_atmosphere_layer_due_to_deep_convecti on -> tendency_of_mass_content_of_water_vapor_in_atmosphere_layer_due_to_deep_ convection tendency_of_water_vapor_content_of_atmosphere_layer_due_to_shallow_conve ction -> tendency_of_mass_content_of_water_vapor_in_atmosphere_layer_due_to_shall ow_convection tendency_of_water_vapor_content_of_atmosphere_layer_due_to_turbulence -> tendency_of_mass_content_of_water_vapor_in_atmosphere_layer_due_to_turbu lence water_content_of_atmosphere_layer -> mass_content_of_water_in_atmosphere_layer water_vapor_content_of_atmosphere_layer -> mass_content_of_water_vapor_in_atmosphere_layer This would require creating a total of 27 aliases. However all the mass content names would then be consistent across the table and their syntax would also be more consistent with existing atmosphere_mass_concentration and atmosphere_number_content names. Having a consistent syntax will reduce the likelihood of introducing duplicate names in the future. Comments on this proposal are invited.
