Record Label : surface_upward_mass_flux_of_nitrogen_compounds_expressed_as_nitrogen
Record Title : Surface Upward Mass Flux of Nitrogen Compounds Expressed As Nitrogen
CF Standard Name : surface_upward_mass_flux_of_nitrogen_compounds_expressed_as_nitrogen
Record Description : The surface called "surface" means the lower boundary of the atmosphere. "Upward" indicates a vector component which is positive when directed upward (negative downward). In accordance with common usage in geophysical disciplines, "flux" implies per unit area, called "flux density" in physics. he phrase "expressed_as" is used in the construction A_expressed_as_B, where B is a chemical constituent of A. It means that the quantity indicated by the standard name is calculated solely with respect to the B contained in A, neglecting all other chemical constituents of A. "Nitrogen compounds" summarizes all chemical species containing nitrogen atoms. 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.
