AB: The concentrations of trace gases, the submicron aerosol size distributions and the chemical composition of aerosols were measured at two coastal sites in Korea: Gosan in Jeju Island during March, as a part of the Atmospheric Brown Clouds-East Asian Regional Experiment 2005 (ABC-EAREX 2005) and Anmyeon-do, the Korea Global Atmospheric Watch Observatory (KGAWO), during October, 2005. New particle formation and growth events occurred around noon and lasted for 4 to 10 hours. For these events, relative humidity was less than 60% and the northwesterly wind was dominant. The air masses were transported from continent and over the Yellow Sea or East Sea. In general, daily mean of PM2.5 mass concentrations decreased. In addition, NOx concentrations remained low and OC/EC ratios were enhanced during the ABC-EAREX 2005. Detailed discussion will be presented in the meeting.
