Short summary

A new emission input dataset that incorporates nitrogen isotopes has been used in the CMAQ (Community Multiscale Air Quality) modeling system simulation to qualitatively analyze the changes in δ¹⁵N values, due to the dispersion, mixing, and transport of the atmospheric NO_x emitted from different sources. The dispersion, mixing, and transport of the atmospheric NO_x were based on the meteorology files generated from the WRF (Weather Research and Forecasting) model.
