[ABSTRACT]Chiba and Manila (Quezon) Cities are two typical coastal cities in east Asia. Aerosol properties of two cities were compared by sampling around the same period (dry season) and analyzed at the same instruments. Aerosol were sampled using two sets of NILU-type samplers for EC/OC analysis (quartz fiber filter) and for ion-chromatography analysis (PTFE filter). Particle size were classified into 3 stages (giant particle; d(diameter) > 10um, coarse particle; 10um > d > 2.5um, fine particle; d< 2.5um). In dry season, the wind direction was north to east in Manila, west to north in Chiba. In both sites, the soil components were most abundant; however there are some differences. In Manila, in all sizes, the soil shows the largest, but in Chiba, in the fine particle it showed small fraction; (NH4)2S04 showed the largest in fine particle in Chiba, but not in Manila. EC/OC were the main components of fine particle in both cities. Sea salt showed larger fraction in larger size. The fraction of giant particle is constantly around 15ｵg/m3 in Manila, but varies 5 to 20ug/m3 in Chiba, especially large in April with larger concentration of soil, probably due to Asian dust.
