Short summary

New particle formation and growth are important processes affecting climate and air quality. A significant fraction of newly formed particles originates from sulfuric acid, water, and ammonia. The present study introduces a new process model for the calculation of aerosol nucleation and growth rates for the sulfuric acid–ammonia system. The thermodynamic parameters enabling these calculations are derived from laboratory (CLOUD chamber) measurements.
