Dear CF-Meta Mailinglist,

As mentioned in the previous e-mail I would like to propose further 
nitrogen-related standard names and two corrections. The full 
definitions are attached in the end of this e-mail and as csv file.


In the last CF standard name update the two names

     
tendency_of_atmosphere_mass_content_of_nitrogen_due_to_dry_deposition
     
tendency_of_atmosphere_mass_content_of_nitrogen_due_to_wet_deposition

were added.

I realized that I made a typo in the descriptions. "nitrage" needs to be 
changed to "nitrate" in the description of both standard names.


Based on these two names, I propose the following new standard names:
  ( 1) 
tendency_of_atmosphere_mass_content_of_oxidized_nitrogen_due_to_deposition
  ( 2) 
tendency_of_atmosphere_mass_content_of_reduced_nitrogen_due_to_deposition
  ( 3) 
tendency_of_atmosphere_mass_content_of_oxidized_nitrogen_due_to_dry_deposition
  ( 4) 
tendency_of_atmosphere_mass_content_of_reduced_nitrogen_due_to_dry_deposition
  ( 5) 
tendency_of_atmosphere_mass_content_of_oxidized_nitrogen_due_to_wet_deposition
  ( 6) 
tendency_of_atmosphere_mass_content_of_reduced_nitrogen_due_to_wet_deposition
  ( 7) 
tendency_of_ocean_mole_content_of_reduced_nitrogen_due_to_deposition
  ( 8) 
tendency_of_ocean_mole_content_of_oxidized_nitrogen_due_to_deposition
  ( 9) 
tendency_of_ocean_mole_content_of_reduced_nitrogen_due_to_dry_deposition
  (10) 
tendency_of_ocean_mole_content_of_oxidized_nitrogen_due_to_dry_deposition
  (11) 
tendency_of_ocean_mole_content_of_reduced_nitrogen_due_to_wet_deposition
  (12) 
tendency_of_ocean_mole_content_of_oxidized_nitrogen_due_to_wet_deposition

There exists already a variable called

     
tendency_of_atmosphere_mass_content_of_noy_expressed_as_nitrogen_due_to_dry_deposition

which is similar to the proposed "oxidized_nitrogen" standard names. 
However, "noy" commonly denotes gaseous species whereas 
"oxidized_nitrogen" denotes gaseous and particulate species.

Reason for (1) to (6): For marine ecosystem modelling, reduced and 
oxizied nitrogen compounds need to be distinguished. Atmospheric 
deposition is one source for marine nitrogen compounds.

Reason for (7) to (12): Consistency. New names (1) to (6) are for the 
output files of chemistry transport models, whereas (7) to (12) are for 
input files of marine biogeochemical models.


Cheers,
Daniel

tendency_of_atmosphere_mass_content_of_oxidized_nitrogen_due_to_deposition
kg m-2 s-1
"Content" indicates a quantity per unit area. The "atmosphere content" 
of a quantity refers to the vertical integral from the surface to the 
top of the atmosphere. For the content between specified levels in the 
atmosphere, standard names including "content_of_atmosphere_layer" are 
used. "tendency_of_X" means derivative of X with respect to time. The 
specification of a physical process by the phrase "due_to_" process 
means that the quantity named is a single term in a sum of terms which 
together compose the general quantity named by omitting the phrase. 
"Deposition" is the sum of wet and dry deposition. Usually, particle 
bound and gaseous nitrogen compounds, such as nitrogen monoxide (NO), 
nitrogen dioxide (NO2), dinitrogen pentoxide (N2O5), nitric acid (HNO3), 
nitrate (NO3-), peroxynitric acid (HNO4), bromine nitrate (BrONO2), 
chlorine nitrate (ClONO2) and organic nitrates (most notably 
peroxyacetyl nitrate, sometimes referred to as PAN, (CH3COO2NO2)), are 
included. The list of individual species that are included in this 
quantity 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.
