Short summary

We developed the localized incremental reactivity (IR) for VOCs in a Chinese megacity and elucidated their applications in calculating the ozone formation potential (OFP). The IR scales showed a strong dependence on chemical mechanisms. Both emission- and observation-based inputs are suitable for the MIR calculation but not the case under mixed-limited or NO_x-limited O₃ formation regimes. We provide suggestions for the application of IR and OFP scales to aid in VOC control in China.
