Abstract
The research was conducted to simulate and interpret the change of $\small{PM_{10}}$ profile by Asian dust using the CALPUFF modeling system for the period April 6 through 18, 2001. The results, which are represented a daily variation of $\small{PM_{10}}$ concentration before and after Asian dust, was located between a minimum concentration of $\small{50{\mu}g/m^3}$ and a maximum concentration of $\small{100{\mu}g/m^3}$, Most concentration peaks in the $\small{PM_{10}}$ profile were shown within a level below 500 m and had a pattern that rapidly increased up the peak and decreased after the peak to 1000 m. Even though the shapes of the vertical profile during Asian dust days were similar to non-Asian dust days, no rapid change vertically was observed. In particular, the vertical profile on 1200 LST and 1800 LST was noticeably shifted to the higher concentrations, which means $\small{PM_{10}}$ in the atmosphere was changed into a vertically and horizontally heterogeneous form under the Asian dust event. Finally, it is con-firmed that the simulation result from CALPUFF might schematically sketched atmospheric $\small{PM_{10}}$ profiles and their change by Asian dust throughout the comparison with profiles of aerosol extinction coefficients, which were acquired from Lidar measurement at KGAWO.
