Abstract. New particle formation (NPF) studies in China were summarized comprehensively in this paper. NPF frequency, formation rate and particle growth rate were closely compared among the observations carried out at different types of sites in different regions of China in different seasons, with the aim of exploring the nucleation and particle growth mechanisms. The interactions between air pollution and NPF are discussed, emphasizing on the properties of NPF under heavy pollution conditions. The current understanding of NPF cannot not be fully explain the frequent occurrence of NPF at high aerosol loadings in China, and possible reasons for this phenomenon are proposed. The effects of NPF and some aspects of NPF research requiring further investigations are also summarized in this paper.

Short summary
The characteristics of new particle formation (NPF) in China, including frequency, formation rate and particle growth rate, were summarized comprehensively and were compared among observations in different environments. The interactions between air pollution and NPF and the possible reasons of more frequent NPF under heavy pollution conditions than current understanding are discussed. Significance and future research directions for NPF study in China are also summarized.
