The underappreciated role of nonvolatile cations in aerosol ammonium-sulfate molar ratios

Hairun Guo, Athanasios Nenes

Overprediction of fine-particle ammonium-sulfate molar ratios (R) by thermodynamic models is suggested as evidence for interactions with organic constituents that inhibit the equilibration of gas-phase ammonia with aerosol sulfate and questions the equilib ...
