Experimental Study on the Effect of Cheong-gye Stream Restoration on Urban Environment (long-path Measurement of Atmospheric Pollutant Species with an Obstruction Flashlight)

The expressway was dismantled in Seoul in July, 2003, and the municipal river was restored in October, 2005. In this study, it is intended that the atmospheric pollutant data and the air temperature data are accumulated in the proof of the relaxation effect of the heat island phenomenon in Cheongecheon. As a method of researching the atmospheric pollutant, the astronomical telescope was used. Furthermore, as a method of the meteorological observation, an observation data of air temperature at 19:30-20:30 in September 24th 2005 was used in Cheongecheon. The purpose of this study is twofold. First, we compare the long-path result with the point data simultaneously measured at groundbased monitoring stations. Second, we analyze quantitative evaluation of the effect of Cheong-gye stream restoration on air quality.By publishing the result of being obtained in this study, it is thought it is useful to the improvement of the consciousness for the environment of the citizen.
