Abstract

|
The characteristics for the aerosol number distribution was studied during spring, 2004 in Incheon. Optical Particle Counter (OPC, HIAC/ROYCO 5230) was used in order to measure the number concentration of aerosol in the range of . The obtained results were compared with data during Asian dust events. The results show that the size resolved aerosol number concentration from OPC measurement has a similar tendency with mass concentration. During Asian dust periods, the number concentrations in large particle increase more than small particles which diameter is less than and the same results were shown when was compared with data compared with non-dust days, Consequently, this study shows that size resolved aerosol number concentration from OPC measurement can be used as a useful tool in comparison of mass concentration data.
