Multiphase buffering by ammonia explains wide range of atmospheric aerosol acidity

Caption

Multiphase buffering effect of emitted ammonia controls aerosol pH, thereby influencing the haze chemistry and formation of aerosol particles, especially nitrate, sulfate and ammonium. It shows a close link between the nitrogen cycle and atmospheric chemistry. The picture shows a hazy day in Guangzhou, China.
