Incomplete Sulfate Aerosol Neutralization Despite Excess Ammonia in the Eastern US: A Possible Role of Organic Aerosol

Acid-base neutralization of sulfate aerosol (S(VI) ≡ H 2 SO 4 (aq) + HSO 4 - + SO 4 2- ) by ammonia (NH 3 ) has important implications for aerosol mass, hygroscopicity, and acidity. Surface network and aircraft observations across the eastern US show that sulfate aerosol is not fully neutralized even in the presence of excess ammonia, at odds with thermodynamic equilibrium models. The sulfate aerosol 15
