Abstract

In situ aerosol optical properties were measured at the Gosan super-site, Korea during Asian Pacific Regional Aerosol Characterization Experiment(ACE-Asia). Size-separated and RH-controlled measurements of ambient aerosol were made by using nephelometer and Particle Soot Absorption Photometer(PSAP) as well as condensation nuclei(CN) counter. Large temporal variability of aerosol optical properties in the marine boundary layer was observed. The concentration of condensation nuclei during Asian dust period was 1.97 times higher than that of the non-dust period. Scattering and absorption coefficients of coarse particles(particle diameter smaller than 10 ㎛) at wavelengths of 550 and 565 mm during the Asian dust period were 122.4 and $24.6\;Mm^{-1}$ that correspond to 3.9 and 3.3 times higher than the non-dust period, respectively. The scattering and absorption coefficients of fine particles(particle diameter smaller than 1.0 ㎛) at the same wavelengths during the Asian dust period were 41.8 and $16.8\;Mm^{-1}$ that correspond to 2.3 and 2.9 times higher than the non-dust period, respectively. Single scattering albedo(SSA) was less than 0.85 in both coarse and fine particle size. This low SSA value implies that radiative heating of the atmosphere due to absorbing aerosol in the east Asian region can be occurred, especially in spring. Aerosol optical properties in this study were also compared with other regional aerosol characterization experiment such as ACE-1, ACE-2, and INDOEX.
