We have simulated the global cycle of reactive nitrogen in a three-dimensional chemistry-transport-deposition model. Our model is a Lagrangian parcel model in which trace species react and are carried in constant-mass air parcels; the parcels are advected by winds calculated by an atmospheric general circulation model (GCM). The GCM calculated winds, clouds, precipitation and other variables at nine levels in the atmosphere with a horizontal resolution of approximately 4.5{degree} latitude and 7.5{degree} longitude. The model includes the basic chemical reactions of NO, NO{sub 2}, and HNO{sub 3} calculated with prescribed distributions of OH and O{sub 3}. The model predicts atmospheric concentrations of NO{sub x} (NO + NO{sub 2}) and HNO{sub 3} throughout the globe at nine altitudes. In addition, deposition of nitrogen in precipitation and in dry processes is also calculated. We present global maps of calculated atmospheric concentration with emphasis on the surface atmospheric concentration of NO{sub x}. Comparisons between calculated and observed atmospheric concentrations and deposition rates are made for several parts of the world. The long-range transport of NO{sub x} is documented from the model by comparing the ratio of surface NO{sub x} concentrations for all sources to those for natural sources only. 40 refs., 6 figs., 2 tabs.
