The Mobile ObserVations of Ultrafine Particles study was a two-year project to analyze potential air quality impacts of ultrafine particles (UFPs) from aircraft traffic for communities near an international airport. The study assessed UFP concentrations within 10 miles of the airport in the directions of aircraft flight. Over the course of four seasons, this study conducted a mobile sampling scheme to collect time-resolved measures of UFP, CO₂, and black carbon (BC) concentrations, as well as UFP size distributions. Primary findings were that UFPs were associated with both roadway traffic and aircraft sources, with the highest UFP counts found on the major roadway (I-5). Total concentrations of UFPs alone (10–1000 nm) did not distinguish roadway and aircraft features. However, key differences existed in the particle size distribution and the black carbon concentration for roadway and aircraft features. These differences can help distinguish between the spatial impact of roadway traffic and aircraft UFP emissions using a combination of mobile monitoring and standard statistical methods.

与飞机和道路交通相关的不同的超细颗粒轮廓

移动观察超细颗粒研究是一个为期两年的项目，旨在分析国际机场附近社区飞机交通对超细颗粒（UFP）的潜在空气质量影响。该研究评估了飞机飞行方向上距机场10英里内的UFP浓度。在四个季节的过程中，该研究进行了移动采样方案，以收集时间分辨的UFP，CO ₂量度。，黑碳（BC）浓度以及UFP尺寸分布。主要发现是，UFP与道路交通和飞机来源均相关，在主要道路（I-5）中，UFP计数最高。仅UFP的总浓度（10-1000 nm）不能区分道路和飞机特征。但是，在道路和飞机特征的粒径分布和黑碳浓度方面存在关键差异。这些差异可以结合移动监控和标准统计方法，帮助区分道路交通和飞机UFP排放的空间影响。
