空气污染是城市地区的一个主要环境问题，对人类健康造成重大不利影响。本研究使用区域-本地耦合系统模拟了英国西米德兰兹地区街道尺度分辨率的空气质量，该系统将区域CMAQ模型与本地ads - urban模型相结合，没有重复计算排放量。CMAQ表示大时空尺度上的离散度，ads - urban表示从明确的点源和道路源出发的局部短期离散度。这两个模型都是根据具有合理性能的观测结果进行评估的，即CMAQ捕获了背景站点测量的空气污染物浓度，而耦合ADMS-Urban RML（区域模型链接）也捕获了路边站点的空气污染浓度，其中局部影响很重要。街道尺度的空气质量地图是由ADMS-Urban RML绘制的，它可以与与健康有关的暴露研究联系起来。WM的耦合空气质量模拟系统是评估潜在的区域和地方空气污染缓解政策的有效工具。
Air pollution is a major environmental concern in urban areas, causing substantial adverse effects on human health. This study simulated street-scale resolution air quality for the West Midlands region in the UK using a regional-to-local coupled system, which combined the regional CMAQ model with the local ADMS-Urban model, without double-counting emissions. CMAQ was used to represent dispersion on large temporal and spatial scales, while ADMS-Urban represents the local short-term dispersion from explicit point and road sources. Both models were evaluated against observations with reasonable performance, i.e. CMAQ captured measured air pollutant concentrations at background sites, while coupled ADMS-Urban RML (Regional Model Link) also captured air pollution concentrations at roadside sites, where local effects were important. Street scale air quality maps were produced from the ADMS-Urban RML, which can be linked to health-related exposure studies. The coupled air quality modelling system for WM serves as an effective tool to evaluate potential regional and local air pollution mitigation policies.
