Dear Philip,
Thanks very much for forwarding these emails to the list and sorry for
not picking up on this thread sooner.
The standard names
tendency_of_mole_concentration_of_particulate_organic_matter_expressed_a
s_carbon_in_sea_water_due_to_net_new_primary_production; mol m-3 s-1
net_new_primary_mole_productivity_of_carbon; mol m-2 s-1
were accepted after discussion in the 'CMIP5 ocean biogeochemistry
standard names' thread.
However, the name
net_primary_mole_productivity_of_carbon_due_to_nitrate
is now being proposed for the second quantity because there is some
confusion as to the precise meaning of 'new' production.
As the accepted names have not yet been added to the standard name table
I think we could change them provided everyone agrees. Both names should
be changed to be consistent with one another. The phrase 'due_to' is
reserved in standard names for describing a process, e.g.
'due_to_convection', so 'due_to_nitrate' doesn't really fit that
pattern. Would
net_primary_mole_productivity_of_carbon_from_nutrients_containing_nitrat
e
or just
net_primary_mole_productivity_of_carbon_from_nitrate_nutrients
be an accurate description?
The first name could then be changed to
tendency_of_mole_concentration_of_particulate_organic_matter_expressed_a
s_carbon_in_sea_water_due_to_net_primary_production_from_{nutrients_cont
aining_nitrate}|{nitrate_nutrients}.
Perhaps John Dunne could also comment on these ideas.
Best wishes,
Alison
