This paper reports on the analysis and findings of the data collected during a mobile air quality campaign commissioned by the City of London Corporation (CoL). This was done using an equipped vehicle capable of taking continuous precision measurements of local air quality while travelling within the City. Several comparative analyses on measured Nitrogen Dioxide (NO₂) data have been performed between Smogmobile data and those available from CoL precision systems as well as with indicative systems, namely Diffusion Tubes, distributed across the City. Key findings highlight that data collected from the Smogmobile, in terms of average concentration of NO₂ across the City (62 µg/m³), are very similar to those obtained by averaging the values from the 48 indicative systems (59.5 µg/m³), with an error of just 4%. Overall, this study demonstrates significant potential and value in using mobile air quality measurements to support assessment of air quality over large areas by Local authorities.

伦敦市本地空气质量（NO2）时空评估的移动监控

本文报告了伦敦金融城（CoL）委托进行的移动空气质量运动期间收集到的数据的分析和发现。这是使用配备齐全的车辆完成的，该车辆能够在市区内行驶时连续精确地测量当地空气质量。在Smogmobile数据与可从CoL精密系统以及整个城市分布的指示系统（即扩散管）中获得的数据之间，对测得的二氧化氮（NO ₂）数据进行了一些比较分析。主要发现强调，从Smogmobile收集的数据以全市NO ₂的平均浓度（62 µg / m ³）与通过平均48个指示系统（59.5 µg / m ³）的值所获得的结果非常相似，误差仅为4％。总的来说，这项研究证明了使用移动式空气质量测量技术来支持地方当局对大范围空气质量评估的巨大潜力和价值。
