Comments "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)."
