$Top: Annual trend of relative differences (p) of 24-hour average ammonium nitrate and ammonium sulfate along with NOx for comparison. Bottom: Day of week profile of differences in mole fractions of Ox and concentrations of ammonium nitrate and ammonium sulfate (ΔC). Summer ammonium nitrate was scaled by 6 for plotting purposes, and ammonium sulfate by 18. Winter months shown on the left, summer months shown on the right. Holidays (“Hol”) are defined in the text.
