报告：马德里中央实施后，阿吉雷埃斯库埃拉斯的PM2 .5浓度的变化
Report: Evolution of the PM2.5 concentration at Escuelas Aguirre after Madrid Central implementation
摘要：
在本报告中，分析了2019年各季度Escuelas Aguirre监测站PM2.5浓度的演变以及与往年各季度浓度差异的重要性。这些时期包括启用马德里中央，这是减少市中心机动车交通和相关污染的一项重大举措。这些时间段对应于2019年第一季度的初始化;以及马德里中心的三个全面运营的季度，2019年第二季度，2019年第三季度和2019年第四季度。Escuelas Aguirre监测站不在马德里市中心，但在2公里外。通过对该监测站PM2.5浓度的分析，可以看出由于交通限制区周围机动车交通量增加而产生的负面影响。该分析基于单样本的二项符号检验。信号样本是通过减去20 xx年和2019年两年内测量的PM2.5日平均浓度生成的。评估了2019年与2010年至2018年期间的成对比较样本。过多的正号或负号表示两年比较中浓度测量值之间的差异很大。相反，积极和消极信号的平衡数量表明该行动没有影响。由于风是一种有效的污染清除剂，在两个时段的比较中，风的强度也被应用了二项式符号检验。这使得我们能够辨别出减轻污染是否与2019年季度的大风日数增加有关。
英文摘要：
In this report, the evolution of PM2.5 concentration at Escuelas Aguirre monitoring station during the quarters of 2019 and the significance of the differences with the concentration of the quarters of previous years is analysed. These periods include the activation of Madrid Central, which is a major initiative for reducing motor traffic and the associated pollution at the city centre. These periods correspond to the initialisation of, 2019Q1; and to tree fully-operational quarters of Madrid Central, 2019Q2, 2019Q3 and 2019Q4. Escuelas Aguirre monitoring station is not inside Madrid Central but 2 km away. The analysis of the PM2.5 concentration at this station allows discerning the rise of negative effects due to an increment of the motor traffic around the traffic restricted area. The analysis is based on the Binomial Sign Test for a Single Sample. The sample of signs is generated by subtracting the daily mean concentration of PM2.5 for the measurements of the period of two years: 20xx and 2019. Samples for the pair-wise comparisons for the year 2019 versus the years of the periods from 2010 to 2018 are evaluated. An excess of positive or negative sign indicates that the differences between the measurements of concentrations in the comparison of two years are significant. Conversely, a balanced number of positive and negative signs points to no impact of the action. Since wind is an efficient pollution remover, the Binomial Sign Test is also applied to its intensity in the two-periods comparison. This allows discerning if the pollution reduction could be associated to a larger number of windy days in the 2019 quarter under comparison.
