Brief summary of different simulations conducted in this work in CMAQ v5.2.1.

Simulations Details
NonPhaseSep Base CMAQ v5.2.1 parameterization assuming homogeneous, internally mixed organic-inorganic fine aerosol, no phase separation (Pye et al., 2017)
PhaseSep2 Additional term in reactive uptake calculation to capture the impact of phase separation and organic coating described in Sect. 2.1–2.3 and 2.5; Zuend and Seinfeld (2012) phase-separation criteria for both liquid and solid or semi-solid particles (see Sect. 2.3)
Emissions Reduction EPA-recommended emission reductions for the year 2025 of 34% and 48 % for NOx and SO2 from base 2013 scenario (see Sect. 2.6)
HighHorg Higher organic-phase Henry’s law coefficient (3 orders of magnitude higher than in PhaseSep or PhaseSep2) (see Sect. 2.6)
PhaseSep All parametrization is the same as in PhaseSep2 except for the sensitivity that Zuend and Seinfeld (2012) phase-separation criteria are not followed for solid or semi-solid particles (see Sect. 2.6)
