Dear Roy,

Thank you for the fast reply.

I agree - it should be consistent for both names - and my preference is 
the same.

Thanks for pointing it out. It was not intentional. I missed the 
sentence. The description should actually be:

"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". "Dissolved inorganic nitrogen" describes a 
family of chemical species which, in an ocean model, usually includes 
nitrite, nitrate and ammonium which act as nitrogen nutrients. 
"Dissolved inorganic nitrogen" is the term used in standard names for 
all species belonging to the family that are represented within a given 
model. The list of individual species that are included in a quantity 
having a group chemical standard name can vary between models. Where 
possible, the data variable should be accompanied by a complete 
description of the species represented, for example, by using a comment 
attribute.


Cheers,
Daniel
