空气污染是现代世界日益严重的问题，对生态系统过程构成重大威胁。虽然了解污染物对自然环境的影响的重要性是显而易见的，但进行严格的实地实验提出了艰巨的挑战。以可控的方式提高露天环境中的污染物浓度是一项复杂的工作。尽管如此，这种真实世界的实验对于揭示空气污染物对生态系统及其功能的真正影响是无价的。现场尺度的测量已经成为促进我们对空气污染物与自然世界之间相互作用的理解的关键途径，为生态系统动力学提供了独特的见解，包括授粉和自然害虫调节等关键过程。在大气和生态研究中，自由空气暴露系统已被证明在提高二氧化碳（CO2）和臭氧（O3）浓度方面是有效的，有助于探索其生态后果。然而，氮氧化物（NOx）是一类具有重要生态和大气相关性的污染物，在很大程度上逃避了实地生态学调查。本文介绍了最近开发的FADOE （Free-Air Diesel and Ozone Enrichment）平台，该平台可以在现场范围内对o3和柴油废气（包括NOx）进行提升。从2023年夏季开始，介绍了该系统的设计、建造和性能数据的综合信息。•空气污染和生态系统功能•臭氧和氮氧化物（NOx）升高•用于现场规模测量的自由空气暴露系统。
Air pollution is an escalating concern in the modern world, posing substantial threats to ecosystem processes. While the importance of comprehending the impact of pollutants on natural environments is evident, conducting rigorous field-based experiments presents formidable challenges. Elevating pollutant concentrations within open air environments in a controlled manner is complex. Nonetheless, such real-world experiments are invaluable for revealing the genuine influence of air pollutants on ecosystems and their functioning. Field-scale measurements have emerged as a pivotal avenue for advancing our understanding of the interactions between air pollutants and the natural world, providing unique insights into ecosystem dynamics, including critical processes like pollination and natural pest regulation. In atmospheric and ecological research, free-air exposure systems have proven effective in elevating carbon dioxide (CO2) and ozone (O3) concentrations, facilitating the exploration of their ecological consequences. Yet, nitrogen oxides (NOx), a class of pollutants with significant ecological and atmospheric relevance, have largely eluded field-based ecological investigations. This paper introduces the recently developed FADOE (Free-Air Diesel and Ozone Enrichment) platform, which allows the elevation of O3and diesel exhaust (including NOx) within a field-scale context. Comprehensive information on the system's design, construction, and performance data from the 2023 summer season is presented.•Air pollution and ecosystem functioning•Elevated ozone and nitrogen oxides (NOx)•Free-air exposure systems for field scale measurements.
