Fig. 2

Except for NO3 radicals, data from 12:00 to 16:00 on day 6 are used. For NO3, data from 23:00 to 03:00 on days 6 and 7 are used. Scenario 2 = base case + NO2, Scenario 3 = base case + O3, Scenario 4 = base case + HCHO, and Scenario 5 = base case + NO2 + O3 + HCHO. The boxplot represents quartiles and median, the red dot is the average, and the gray dots are the individual data points (6 per hour for 4 h, yielding 24 points). Scenarios are presented in Table 1. Statistical difference between the base case and other scenarios is presented as p-values below 0.05 (*), 0.01 (**), 0.001 (***), and 0.0001 (****). Ns means non-statistical difference. Time series plots are available in Figs. S7–S12.
