AB  - New particle formation (NPF) has a great impact on regional and global climate, 
      air quality and human health. This study uses a Scanning Mobility Particle Sizer 
      (SMPS) for simultaneous measurement of particle number size distribution (PNSD) 
      in wintertime to investigate NPF in the coastal city of Xiamen. The mean particle 
      number concentration, surface area concentration and volume concentration were 
      7.25 x 10(3) cm(-3), 152.54 mum(2) cm(-3), and 4.03 mum(3) cm(-3), respectively. 
      Particle number concentration was mainly influenced by the nucleation mode and 
      the Aitken mode, whereas the main contributor to particle surface area 
      concentration and volume concentration was accumulation mode particles. The 
      frequency of NPF events occurred was around 41.4% in December 2019. The typical 
      growth rates of new formed particles were 1.41-2.54 nm h(-1), and the observed 
      formation rates were 0.49-1.43 cm(-3) s(-1). A comparative analysis of conditions 
      between event and non-event days was performed. The results emphasized that air 
      temperature, UV radiation and relative humidity were the most decisive 
      meteorological factors, and NPF events usually occurred under clean atmospheric 
      conditions with low PM concentrations. Although condensation sink was high when 
      NPF event occurred, the level of SO(2) and O(3) concentration was also high.
