Because ambient ozone concentrations are so strongly influenced by stochastic and seasonal variations, it is difficult to assess the effectiveness of regulatory controls in improving ambient ozone air quality. The purpose of this paper is to present a method for moderating the influence of meteorological fluctuations on ambient ozone levels. Techniques presented here account for temperature and other meteorological variables that affect ambient ozone concentrations. To this end, we have examined the correlation between several meteorological variables and ozone concentrations. In addition, we have evaluated trends in ozone time series after removing the effects of these variables on ozone concentrations. The results indicate that inclusion of two meteorological variables strengthens the relationship between ozone and meteorological effects. Moreover, the meteorologically-independent ozone time series at one of the locations studied had a significant trend that was not detected in temperature-independent ozone concentrations.
由于环境臭氧浓度受随机和季节变化的影响很大，因此难以评估监管控制措施在改善环境臭氧空气质量方面的有效性。本文的目的是提出一种方法，以减轻气象波动对环境臭氧水平的影响。这里介绍的技术考虑了影响环境臭氧浓度的温度和其他气象变量。为此，我们研究了几个气象变量与臭氧浓度之间的相关性。此外，我们还评估了去除这些变量对臭氧浓度的影响后臭氧时间序列的趋势。结果表明，纳入两个气象变量增强了臭氧与气象效应之间的关系。此外，在所研究的一个地点，与气象无关的臭氧时间序列有一个显著趋势，而在与温度无关的臭氧浓度中未检测到该趋势。
