This study presents characteristic of PM-10 concentration in association with Spatial Synoptic Classification(SSC) in Seoul and Jeju. The DM(Dry Moderate)’s frequency is the most high among the SSC in Seoul and Jeju. Daily PM-10 concentrations were grouped by SSC. DT(67 ㎍/㎥) is the highest mean among SSC in Seoul. DM & DT(48 ㎍/㎥) are is the highest mean among SSC in Jeju. Our result show that SSC’s monthly frequency SSC and monthly PM-10 concentration are a weak correlation.

This study examined the characteristics of PM concentration distribution monitored by its size at seven National Atmospheric Monitoring Stations from the March 2008 to May 2009. And it found that PM concentration showed a bimodal shape with two peaks : one between 0.32 and 0.56 ㎛ and the other between 3.2 and 5.6 ㎛. The study reckons that the concentration of PM-2.5 accounted for larger share than the rest of the particles since the highest concentration appeared in the range of 0.32∼0.56 ㎛, and the second highest on was between 1.8∼3.2 ㎛. The size of particles differed by station, particularly between 0.32 and 0.56 ㎛, and 0.56 and 1.0 ㎛. Other size ranges showed similar concentration ratios. Diameter interval appears relatively large difference by station in section 0.32∼0.56 ㎛ and 0.56∼1.0 ㎛, concentration ratios similar to other section. Though the size distribution of particle concentration is similar in seven stations, it is appeared that relatively large difference is observed in section 0.32∼0.56 ㎛ and 0.56∼1.0 ㎛. Considering the fact that emission sources emit different size of particles according to their chemical and physical formation process, this study assumes that there are differences in the size-segregated particle concentration as the size distribution of each station reflects the characteristics of emission in a region. The particle concentration of Seoul Metropolitan Area (SMA) was high in October 2008 and April 2009, in particular during Asian dust events.
