Validation and optimization of the drone air quality measurement system MesSBAR

In the project MesSBAR (Automated airborne measurement of pollution in the near-earth atmosphere in urban areas), unmanned aerial systems and specially adapted air quality measurement technology were developed to carry out measurements upwind and downwind of pollution sources in urban areas, industrial plants and traffic routes. To validate and optimise the measurement technology and flight systems, two short measurement campaigns were carried out in 2021 near Wesseling next to the motorway A555 (North Rhine-Westphalia - Germany). There, the Federal Highway Research Institute (BASt) operates two measurement containers next to the highway, which were used for the validation. Various flight profiles were tested. It was found that only for vertical ascents at a constant speed, useful results of the air quality measurements could be determined. The measurement data from these flights are published in this data publication.本项目MesSBAR（城市近地大气污染机载自动化测量）研发了无人航空系统与定制化空气质量测量技术，用于在城市区域、工业厂区及交通干线的污染源上风与下风方向开展污染测量工作。 为验证并优化测量技术与飞行系统，2021年在德国北莱茵-威斯特伐利亚州韦瑟林附近的A555高速公路旁开展了两次短期测量作业。彼时，联邦公路研究所（Federal Highway Research Institute, BASt）在该高速公路旁部署了两座测量方舱，本研究借助其完成了技术验证。本次作业测试了多种飞行剖面，研究发现仅当以恒定速度进行垂直爬升时，方可获取有效的空气质量测量结果。本次飞行获取的测量数据已收录于本数据集出版物中。
