二氧化硫日均值时间序列的傅立叶级数模型

Fourier Model for the Time Series of SO_2 Daily Average Concentrations

文章运用傅立叶级数展开方法,提出一种生成傅立叶级数的模型,并用模型计算广州市2004~2007年二氧化硫日均值时间序列的傅立叶级数模型,得到二氧化硫浓度存在23、47d等变化周期,并对后续的时间二氧化硫浓度进行预测。

Based on the Fourier series, a Fourier model was established for the time series of SO2 daily average concentrations during 2004～2007 in Guangzhou. Two change cycles of 23 days and 47 days were found, and used for forecast calculation of SO2 daily average concentrations.
