城市臭氧(O-3)污染受野火烟雾传输的影响，但观测到的影响是高度可变的。我们调查了2013-2017年7-9月期间美国西部18个城市烟雾对O-3的影响，利用空气质量系统站点的地面监测数据，使用基于卫星的危险地图系统(HMS)火灾和烟雾产品来识别头顶上的烟雾。我们提出了四个关键发现。第一，O-3和PM2.5(颗粒物
Urban ozone (O-3) pollution is influenced by the transport of wildfire smoke but observed impacts are highly variable. We investigate O-3 impacts from smoke in 18 western US cities during July-September, 2013-2017, with ground-based monitoring data from air quality system sites, using satellite-based hazard mapping system (HMS) fire and smoke product to identify overhead smoke. We present four key findings. First, O-3 and PM2.5 (particulate matter
