Deskripsi
Concentrations of condensation nuclei (>0.01 μm in diameter) and of aerosol particles larger than 0.3 μm in diameter were monitored at Syowa Station from February, 1996. Number concentrations of condensation nucleus were high in summer and low in winter. Concentrations increased at the rate of several partcles cm^3 per year. On the other hand, the concentrations of fine particles (>0.3 μm) and coarse particles (>1.0 μm) were low in summer and high in winter. Concentrations of fine particles 0.3 μm and larger after July were double those before July.
