Fig. 6: Spatial distributions of dominant precursors influencing NO3− and PM2.5 under emission reduction scenarios of NH3, NOx, VOC, and SO2.

Fig. 6

The maps display the dominant precursors of NO3− (a–d) and PM2.5 (e-h) for different scenarios and regions. The white shadedareas represent the relative difference value of responses to different precursors is less than 5%.
