Forecasting peak ozone levels

Abstract Box-Jenkins (1970) time series models are used to predict peak afternoon O 3 levels. Data sets from three monitoring stations in Brisbane, Queensland, Australia, are used in the analysis, one of the stations being inner-city and the others being outer-city. It is found that univariate models using only the peak O 3 data-set at a site to predict future peak O 3 levels are unsatisfactory. However bivariate models using peak O 3 data from one site to predict peak O 3 levels at another site yield good results. However it is clear that these results only arise because the O 3 is formed in a well mixed layer over the region leading to a high degree of correlation between O 3 peaks throughout the region.
