The formation of new particles in the atmosphere due to nucleation and the subsequent growth of these particles is an important process that regulates the number concentrations of aerosol particles. This process is linked to cloud processes and therefore to climate via the conversion of new particles to cloud condensation nuclei. In this article, recent field, laboratory, and modeling studies on the formation of new particles in the atmosphere are reviewed from the viewpoints of nucleation and the initial condensational growth caused by low-volatile gaseous precursors. The topics in this article include the nucleation involving sulfuric acid vapor, condensational growth of new particles caused by low-volatile organic and iodine compounds, and the contribution of ion-induced nucleation to particle formation.
