Short summary

This study linked a long-term and near real-time measurement of NH₃ at one of China’s flagship supersites with a vehicle source-specific campaign performed inside and outside of a major freeway tunnel in Shanghai. Our results clearly show that vehicle emissions associated with combustion are an important NH₃ source in Shanghai urban areas and may have potential implications for PM_2.5 pollution in the urban atmosphere.
