기상상태가 초미세먼지농도에 미치는 영향에 대한 분석

다국어 초록 (Multilingual Abstract)

The fine dust problem is getting serious that deteriorates the quality of life. Recently, the concentration of PM10 and PM2.5 has increased, and it has been known that it affects not only the public health but also the national economy. KORUS-AQ(Korea-United States Air Quality Study) conducted in 2016 reported that the contribution of domestic emission sources for the fine fust pollution dominate other sources from abroad. In addition, research has also been reported that the primary reason for the concentration of fine dust is wind speed in weather conditions. In this paper, the generalized additive model was applied to investigate how the weather conditions such as wind direction and wind speed affect the PM2.5 concentration without consideration of the emission sources. The result of analysis showed that not only wind speed, but also wind direction influenced the concentration of PM2.5, mainly affected by southwest and west wind in spring, summer and fall, and a wide range from southeast to west wind in winter. To reduce the concentration of the fine dust, the factors affecting the concentration of the fine dust should be identified clearly, and the analysis results of this paper can be contributable.
