Atmospheric aerosols influence Earth’s climatic system and human health. Role of aerosols in climatic system still includes uncertainties strongly influencing model simulations (Zhao et al.
2018). One of the uncertainties is caused by secondary aerosol formation and their consequent growth. Nucleation of aerosol particles is a process determined by presence of aerosol precursors in atmosphere and by ambient atmospheric conditions (Dada et al. 2017).
Since new particle formation (NPF) events have been observed in many types of environment (Kulmala et al. 2004), we have focused on NPF events at background station in the Czech Republic, representative for central European region. In this study we investigate NPF process of aerosol clusters from 1.2 nm in size.
