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 Earth. Thus Nr includes inorganic reduced forms of N (e.g. NH 3 and NH + 4 ) inorganic oxidized forms (e.g. NOx HNO 3 N 2 O and NO – 3 ) and organic compounds (e.g. urea amines and proteins) by contrast to unreactive N 2 gas.
