Short summary
For the first time, the interaction between ammonia and secondary organic aerosol (SOA) is integrated in an air quality model and investigated on a national scale. Our original analysis from simulation results indicates that a significant reduction in gas-phase ammonia is possible due to its uptake onto SOA. Significant impact is also observed in the concentration of particulate matter, with a distinct spatial pattern over different seasons.
