Abstract. Nitrogen oxides (NOx = nitric oxide (NO) + nitrogen dioxides (NO2)) are important trace gases that affect atmospheric chemistry, air quality and climate. Contemporary development of NOx emissions inventories is limited by understanding of the roles of vegetation (net NOx source or net sink), gasoline and diesel in vehicle emissions, and application of NOx emission control technologies. In this study, we used the nitrogen stable isotope composition of NOx (δ15N(NOx) to resolve the uncertainties in NOx emission sources, by incorporating 15N into the US EPA trace gas emission model SMOKE (Sparse Matrix Operator Kernel Emissions) and compared simulated spatiotemporal patterns in NOx isotopic composition with corresponding atmospheric measurements in West Lafayette, Indiana, USA. The results indicate potential underestimation of emissions from soil, livestock waste, off-road vehicles, and natural gas power plants and the potential overestimation of emissions from on-road vehicles and coal-fired power plants.
