COVID-19: Probing Air Quality Controls in the Oxford-Milton-Keynes-Cambridge Arc

英国城市经常超过空气质量（AQ）合规限值。AQ的持续改善将被某些地区的计划增长所抵消。在污染物排放迅速变化的时期进行更详细的观察，将扩大我们对人类活动、污染物排放和AQ控制措施之间复杂相互作用的理解。重点将是颗粒物（PM）和气态污染物的不同反应。COVID-19期间提供了一个前所未有的机会，进行额外的测量，以阐明影响英国空气质量和健康的因素。克兰菲尔德大学（CU）是一个受控的混合（城市和农村）在ARC的心脏网站。它有一个自成一体的校园，具有独特的基础设施，场地类型和设施的组合。克兰菲尔德城市观测基准站正在运行，多物种传感器可立即使用。在该项目中，这些单位将尽快部署在牛津-米尔顿凯恩斯-剑桥弧（ARC）的指定地点，以便在COVID-19限制措施实施和放松期间的低交通和工业活动期间提供详细的观测记录。可以提供关于空气质量与放宽社交距离措施之间相互作用的实时信息。在已知干预措施期间进行的这些测量将为ARC的基础设施规划和低排放区的设计以及更普遍的空气质量政策提供信息。这些数据将可供研究人员使用，研究这些措施的前/中/后效果。

UK cities regularly exceed air quality (AQ) compliance limits. On-going improvements in AQ will be offset by planned growth in some regions. More detailed observations during a period of quickly changing pollutant emissions would expand our understanding of the complex interactions between human activities, pollutant emissions and AQ control measures. A focus will be the differing responses of particulate matter (PM) and gaseous pollutants. The COVID-19 period provides an unprecedented opportunity for additional measurement to illuminate factors which influencing UK air quality and health.Cranfield University (CU) is a controlled mixed (urban and rural) site in the ARCs heart. It has a self- contained campus with a unique combination of infrastructure, site types and facilities. The Cranfield Urban Observatory reference station is operating, and multi-species sensor units are available for immediate use. In this project, these units would be deployed as soon as possible at identified sites across the Oxford-Milton Keynes-Cambridge Arc (ARC) in order to provide a detailed observational record during a period of low traffic and industrial activity while COVID-19 restrictions are in place and being eased. Real-time information can be provided on the interaction between air quality and the easing of social distancing measures. These measurements made during a period of known intervention measures will inform infrastructure planning for the ARC and the design of Low Emission Zones and air quality policy more generally. The data will be available for use by researchers looking at before/during/after effects of these measures.
