도시 대기질 모델의 상호 비교연구 = Inter-comparison of Urban Air Quality Models

다국어 초록 (Multilingual Abstract)

Two air quality models, ISCLT3 and CDM2, are inter-compared by the analysis of computer program algorithms and modeling results of Seoul Metropolitan Area.
Two models use almost similar algorithm such as Gaussian type plume dispersion, meteorological consideration, plume buoyance effect etc..
The main difference is that ISCLT3 includes the rolling terrain effect but CDM2 does not.
Model results of Seoul Metropolitan Area in 1996 showed that the ISCLT3 result was much closer to the measured result(under control of Seoul City Government and Han-River Environmental Management Office) than the CDM2 result in terms of the Relative Error and Root Mean Square Error(RMSE)
The Average Relative Error of ISCLT3 was -4.15% while that of CDM2 was -64.48%.
Therefore ISCLT3 is believed to be a better option in air quality modeling of Seoul Metropolitan Area which is composed of rolling terrains.
