Abstract

The monthly air quality index (AQI) derived from ground observation stations that obtained daily air pollutants information for 1990- through 2010 was analyzed in this study. AQI was evaluated using the common comparative index method presented by the U.S. Environmental Protection Agency (USEPA), and a statistically based approach was used for predicting the AQI value. With the first method, AQI was predicted using the USEPA subindex formula for different pollutants, such as particulate matter and sulfur dioxide, which contribute the most to air pollution. A combination of the principal component analysis (PCA) and multiple linear regression (MLR) methods were used with the measured values of climate variables obtained from the ground stations for the most effective contributors and a prediction was modelled. The results of these two methods were compared and evaluated for consistency. Two methods were presented for determining the AQI value. According to the findings, the common comparative index method was consistent with the statistical prediction models, and the best results were obtained using PCA models with varimax rotation.

模拟土耳其博卢的空气质量指数
本研究分析了1990- 2010年逐月空气质量指数(AQI),该指数由地面观测站获取每日空气污染物信息。采用美国环境保护署(USEPA)提出的通用比较指数法评价AQI,并采用基于统计的方法预测AQI值。在第一种方法中,AQI是根据USEPA针对不同污染物(如颗粒物和二氧化硫)的分类指数公式来预测的,这些污染物对空气污染的影响最大。采用主成分分析(PCA)和多元线性回归(MLR)相结合的方法,结合地面站获得的气候变量实测值对最有效的贡献因子进行了预测,并对预测结果进行了建模。对两种方法的结果进行一致性比较和评价。提出了两种测定AQI值的方法。结果表明,常用的比较指数法与统计预测模型吻合较好,采用变大旋转的PCA模型效果最好。
