EMAC uses a modal representation of aerosols dynamics (GMXe) that describes the aerosol size distribution as seven interacting log-normal distributions, of which four modes are soluble and three modes are insoluble. New particles are added directly to the nucleation mode. The applied model setup ...
Precipitation reactions consist of soluble ionic compounds forming an insoluble ionic precipitate. Neutralization reactions involve an acid and base reacting together to form salt and water. Neither precipitation nor neutralization r...
H2SO4–NH3nucleation dominates in regions with low ammonia (below around 1.0 × 108 cm−3, or 12 pptv), whereas HNO3–H2SO4–NH3nucleation dominates at higher ammonia levels
