초록

동아시아에서 광역적인 대기오염 이동과 한반도 유입을 인공위성과 지상 관측을 통해 5개의 사례를 분석하였다. 이 사례들은 주로 중국 대륙의 도시와 산업지대에서 배출된 오염물질들이 황해를 지나 한반도에 상륙 및 통과하는 광역적인 대기오염 이동이다. NOAA인공위성 관측 자료의 분석은 가시영역과 적외선 영역의 3개 채널을 합성하여 영상을 만들고, 황해 위에서 대기오염의 분포와 이동을 구별해 낼 수 있었다. 또한 청원의 배경관측지점에서 대기오염의 지상 관측 자료는 인공위성 관측 자료와 비교하여 검증하는데 매우 가치가 있었다. 특히, 광역적 대기오염의 이동 사례에서는 $PM_{10}$$PM_{2.5}$ 농도의 차이가 적으면서, $PM_{2.5}$값이 높게 증가한다. 그러나 황사의 경우는 $PM_{10}$ 농도가 훨씬 높게 관측되어 $PM_{2.5}$와의 차이가 매우 큼이 특징적이다. 2006년 1월 27일의 사례에서는 중국 발원의 광역적 대기오염이 한반도의 중부 및 남서지역으로의 유입을 인공위성뿐 아니라 여러 지상관측소들에서 순차적으로 관측할 수 있었다. 북북서 기류가 제주도 한라산을 넘어서 풍하측 멀리까지 구름을 소산시키고 대기오염을 감소시키며, 카르만 소용돌이를 만들고 있었다.

Five episodes of the large-scale transport of air pollutants in East Asia and its inflow into the Korean Peninsula have been analyzed through satellite and ground observations. These episodes include regionally polluted continental airmass, which is created by the pollutants produced in the cities and the industrial regions in China, to land on or pass through the Korean Peninsula by way of the Yellow Sea. The analysis of the NOAA satellite observation data made it possible to create images by combining 3 channels of visible and infrared ray ranges and also to identify the distribution and the transport of the air pollution mass over the Yellow Sea. The ground observation data of the air pollutants gathered in Chongwon were found highly valuable in verifying the information in comparison with ones from the satellite. Especially, regarding the episodes of large-scale transport of the air pollutants, the difference of concentration between $PM_{10}\;and\;PM_{2.5}$ was found small with the increase of $PM_{2.5}$ value. The concentration of $PM_{10}$ in the episode of yellows and, however, was found much higher than that of $PM_{2.5}$. In the episode of 27 January 2006, the inflow of the regionally polluted continental air mass into the central and southwestern region of the Korean Peninsula was observed sequentially in the various ground observatories as well as by the satellite. The north-northwest airflow dissipated the clouds over from Mt. Halla in Jeju Island up to far downwind, reduced air pollution, and created von $K\acute{a}rm\acute{a}n$ vortex.
