Abstract
|
|
|
The concentration of sulfur dioxide in the atmosphere was predicted by using one of air pollutants dispersion modeling programs named TCM(Texas Climatological Model) and the correlation between the meteorological factors and the concentration of air pollutant(S0₂) was studied.
The results are as follows:
For the Hak-Sung Dong site in Wonju city, the correlation coefficient between the measured and calculated concentration was 0.904. The more sunshine was, the lower the concentration of sulfur dioxide was.
The months with greater rainfall showed that the measured concentration of sulfur dioxide was much lower values than the predicted concentration. Although in April the precipitation was smaller than in summer, the wet deposion ratio in April was much higher than any other months, due to the sulfur dioxide that was adsorbed on particulate matter and moisture was transported during the period of loess(yellow sand phenomena) from China.
