ABSTRACT
Different time series analysis of daily air pollution of Isfahan city were performed in this study. Descriptive analysis showed different long-term variation of daily air pollution. High persistence in daily air pollution time series were identified using autocorrelation function except for SO[2] which seemed to be short memory. Standardized air pollution index [SAPI] time series were also calculated to compare fluctuation of different time series with different levels. SAPI time series indicated that NO and NO[2], CH4] and non-CH[4] have similar time fluctuations. The effects of weather condition and vehicle accumulation in Isfahan city in cold and warm seasons are also distinguished in SAPI plots
