"The term reactive nitrogen (Nr) as used in this paper includes all biologically active, photochemically
reactive, and radiatively active N compounds in the atmosphere and biosphere of the
Earth. Thus Nr includes inorganic reduced forms of N (e.g., NH3, NH4+), inorganic oxidized
forms (e.g., NOx, HNO3, N2O, NO3
), and organic compounds (e.g., urea, amines, proteins,
nucleic acids). Note that this definition is much broader than the term ‘reactive N’ as defined by the
atmospheric chemistry community – they define reactive N as NOy, which is any N–O combination
except N2O (e.g., NOx, N2O5, HNO2, HNO3, nitrates, organic nitrates, halogen nitrates, etc)." See notes beneath table |
