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) |
