제주도 고산지역 CO2 농도의 단기 변동에 영향을 미치는 요인 분석

초록

This study examined the short-term variability of CO2 concentrations measured at the Gosan site (33˚17′N, 126˚10′E) in Jeju, Korea for the last 9 years from 2002 to 2010. The weekly distribution shows higher CO2concentrations during weekends than weekdays which implies the impact of local emissions because Jeju Island isone of the top tourist attraction in Korea. In diurnal variation, CO2 concentration reached the maximum at 6 am andthe minimum at 1 pm. The high CO2 concentrations were mostly associated with lower wind speed (below 4 m/s)and easterlies, which was typical of summer night. In other seasons, however, the high concentrations wereencountered under strong westerlies (8~16 m/s), which implies the influence of Chinese outflows. CO2 concentrationswere found to be highly correlated with meteorological parameters including wind speed, temperature,humidity, and solar radiation except for winter.
