摘要: Field observations to investigate the correlation between New Particle Formation (NPF) and long-range transport of air pollutants in East Asia region were carried out on a rural Island Japan East-China Sea (Fukue Island, 32.8°N, 128.7°E) over three periods (February 23 March 7, 2013; November 7 20, 2 24, 2014). Frequent NPF events identified (16 50 days), typically association with sudden increases particle number concentrations successive growth particles mobility diameters several tens nanometers. The classified into two types (A B) according initially detected sizes (onset diameters). Type-A consisted strong onset as small 5 nm. Type-B whose (<10 nm) was not clearly identifiable. correlations SO2 concentrations, solar radiation, PM2.5 chemical composition analyzed based events.
