Ozone precursor emissions and meteorological conditions have large impact on ozone concentrations. In this research, Data referring to an approximately 14-year period (1996~ 2009) are analyzed in order to estimate the trend of the daily maximum hourly value of ozone concentration at national capital region. A Kolmogorov-Zurbenko (KZ) filter is applied to remove the short-term component from the raw time series of ozone and meteorological variables. Meteorological effects are removed from filtered ozone series using multiple linear regression based on meteorological variables. The results show significant differences in local ozone concentrations. Especially, Ulsan area shows continuously increasing trend in ozone concentrations.
