Short summary

We developed an observation-based method to investigate the sensitivity of ozone formation to precursors during two elevated ozone episodes observed at 77 stations in Guangdong, China. We found approximately 67 % of the station days exhibit ozone formation sensitivity to NO_x, 20 % of the station days are in the transitional regime sensitive to both NO_x and volatile organic compounds (VOCs), and only 13 % of the station days are sensitive to VOCs.
