Nitrogen oxides are important for global photochemistry because they determine whether O{sub 3} is produced or destroyed. In this paper, we describe our simulations of the global cycle of reactive nitrogen. We use a three-dimensional chemistry-transport-deposition model. Our model is a Lagrangian model in which trace species react and are carried in constant-mass air parcels; the parcels are advected by winds calculated by the NCAR Community Climate Model (CCM), a nine-layer general circulation model. In Section 2, we describe the model, together with our specification of the reactive nitrogen sources. A comparison of our predicted concentrations and deposition amounts with measurements appears in Section 3. Section 4 describes our model results for predicted distributions, while Section 5 describes our results for deposition. Section 6 summarizes a regional analysis of sources and deposition. Our conclusions appear in Section 7. 42 refs., 9 figs., 5 tabs.
