Cheng (2001) noted the lack of a clear statistical correlation between a single meteorological variable and ozone concentration. The orographic effect and the long-range transport of ozone are critical factors in studying ambient ozone levels. Glavas and Sazakli (2011) reported that in cold months, the concentration of transported ozone was larger than locally formed ozone, whereas in the warm months, more ozone formed locally. Gao (2007) applied functional data analysis techniques to hourly resolved ozone and nitrogen oxide (NOx) measurement data, examining diurnal ozone cycles and their functional characteristics (ozone accumulation and destruction rates), and closely linking them to transportation emissions. The results supported the findings of previous researchers.
