Short summary

Using an updated soil reactive nitrogen emission scheme in the Unified Inputs for Weather Research and Forecasting coupled with Chemistry (UI-WRF-Chem) model, we investigate the role of soil NO and HONO (Nr) emissions in air quality and temperature in North China. Contributions of soil Nr emissions to O₃ and secondary pollutants are revealed, exceeding effects of soil NO_x or HONO emission. Soil Nr emissions play an important role in mitigating O₃ pollution and addressing climate change.
