Fig. 5: Modeled RIR values for PAN precursors and net production rate of O3.
From: Trends of peroxyacetyl nitrate and its impact on ozone over 2018–2022 in urban atmosphere
a Average RIRs values for major precursors of PAN and b average PnetO3 with and without PAN mechanisms in each summer from 2018 to 2022. The simulation period was daytime from 6:00 to 18:00. The error bars represent a standard deviation. The statistic of significance employed here is the pair-sample t-test. * and *** indicate the significance levels p < 0.05 and p < 0.001, respectively.
