In order to improve an accuracy of the real-time odor dispersion modeling system, a sensitivity of CALMET model with different input meteorological data was studied. The performance of CALMET model was tested by comparing the model predictions with the observations at the Daedeok Industrial Complex in Daejeon Metropolitan City. It is shown that the CALMET model with WRF (Weather Research and Forecasting) input data of GFS (Global Forecast System) depicts the measurements better than that of RDAPS (Regional Data Assimilation and Prediction System). The CALMET model could be further improved by selecting options of Divergence minimization, Froude number adjustment and Slope flows without choosing Kinematic Effects in the modeling procedure.

CALMET의 입력기상자료 형태와 CALMET 모델링시 여러 선택변수에 대해서 민감도를 분석하였다. 민감도 분석은 대전광역시 대덕산업단지에 설치된 기상 측정자료와 모델링 결과를 비교하여 그 차이를 평가하였다. CALMET 모델의 입력기상자료는 GFS가 보다 정확한 것으로 파악되었고, CALMET 모델링시에 Kinematic Effects는 적용하지 않고, Divergence minimization, Froude Number Adjustment, Slope Flows 만을 적용한 경우에 정확도가 높아지는 것으로 나타났다
