We present optical and microphysical particle properties of aerosol retrieved by multi-wavelength Raman lidar at Anmyun island ($36.32^{circ}N$, $126.19^{circ}E$), Korea. The results present aerosol properties in various height layers of the atmospheric pollution layers observed over the Korean peninsula on eight consecutive days (27, 28, 29, 30 and 31 May, 4, 5 and 7 June) in 2005 at Anmyun island. We found anthropogenic pollution on 27, 28, and 29 May and local haze on other measurement days. The origin of the particle plumes was determined by simulations of FLEXPART. The source regions of the particles resulted in rather clear differences between the optical and microphysical properties of the pollution layers. The single-scattering albedo of anthropogenic aerosols from China ($0.91{pm}0.01$ at 532 nm) were lower than the single-scattering albedo of local haze aerosols ($0.95{pm}0.01$ at 532 nm). Local haze aerosols show larger effective radii of $0.24{pm}0.02;{mu}m$ at relative humidity of 55~75%. The effective radii of anthropogenic aerosols are $0.20{pm}0.2;{mu}m$ and $0.27;{mu}m$ at relative humidity of 25~50%.
