This study was carried out to estimate the emission reduction rates for the regional allowableemissions by special measures to achieve the target air quality in Seoul Metropolitan Area(SMA).A modeling system was designed to validate the details in enforcement regulations set up bylocal governments based on the current status and plans for air quality improvement.Modeling system was composed of meteorological model (MM5), emission model (SMOKE),and air quality model (CMAQ). Predicted results by this system show quiet well not only dailyair pollutants concentration but also the tendencies of wind direction, wind speed andtemperature.To achieve the target air quality in Seoul Metropolitan Area (SMA), emission allowances areestimated by seasons and regions. Referring to the base year 2002, it was estimated thatemission reduction rates to achieve the intermediate goal in 2007 were 14.2% and 16.6% forNOx and PM10, respectively. It was also estimated that 52% of NOx and 48% of PM10reductions from the base year 2002 would be required to accomplish the air qualityimprovement goal of 22 ppb for NO2, and 40 mg/m3for PM10 in year 2014.To improve NO 2 and PM 10 concentration through emissions reduction policies, it was foundthat emissions reduction for the on-road mobile sources would be the most effective in SMA.
