Dear John, I was looking again at the biogeochemistry names in preparation for adding them to the CMIP5 output document as accepted standard names. I am concerned that we may have given the wrong names to some of the vertically integrated rates of change in the top 100m of the ocean. Please can you advise on the definitions. Currently the names are listed as:
tendency_of_ocean_mole_content_of_dissolved_inorganic_carbon tendency_of_ocean_mole_content_of_dissolved_inorganic_nitrogen tendency_of_ocean_mole_content_of_dissolved_inorganic_phosphorus tendency_of_ocean_mole_content_of_dissolved_inorganic_iron tendency_of_ocean_mole_content_of_dissolved_inorganic_silicon integral_wrt_depth_of_tendency_of_sea_water_alkalinity_expressed_as_mole _equivalent tendency_of_ocean_mole_content_of_dissolved_inorganic_carbon_due_to_biol ogical_processes tendency_of_ocean_mole_content_of_dissolved_inorganic_nitrogen_due_to_bi ological_processes tendency_of_ocean_mole_content_of_dissolved_inorganic_phosphorus_due_to_ biological_processes tendency_of_ocean_mole_content_of_dissolved_inorganic_iron_due_to_biolog ical_processes tendency_of_ocean_mole_content_of_dissolved_inorganic_silicon_due_to_bio logical_processes integral_wrt_depth_of_tendency_of_sea_water_alkalinity_expressed_as_mole _equivalent_due_to_biological_processes The first two names are defined as follows: tendency_of_ocean_mole_content_of_dissolved_inorganic_nitrogen 'Net time rate of change of dissolved inorganic carbon in upper 100m' and tendency_of_ocean_mole_content_of_dissolved_inorganic_phosphorus 'Net time rate of change of nitrogen nutrients (e.g. NO3+NH4) in upper 100m'. If these quantities should be interpreted as the time rate of change of the vertically integrated mole_concentration, then these names are correct. However, the remainder of the names have definitions along the lines of: tendency_of_ocean_mole_content_of_dissolved_inorganic_phosphorus 'Vertical integral of net time rate of change of phosphate in upper 100m', which is clearly the vertical integral of the rate of change and not the rate of change of the vertical integral. I don't think those two things are identical, are they? If the order of the calculation is important then I think we should adopt the pattern used in the alkalinity names for all these names, i.e., integral_wrt_depth_of_tendency_of_mole_concentration_of_dissolved_inorga nic_phosphorus_in_sea_water, etc. Do you agree?
