Drone air quality measurements during flight MesSBAR_2021-06-01_flight5

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 motorway, 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.

在城市区域近地大气污染自动化机载测量项目（MesSBAR）中，研发团队开发了无人航空系统与专用适配型空气质量测量技术，用于在城市区域、工业厂区及交通沿线的污染源上风侧与下风侧开展测量工作。为验证并优化测量技术与飞行系统，项目组于2021年在德国北莱茵-威斯特伐利亚州韦瑟灵镇紧邻A555高速公路的区域开展了两次短期测量航次。当地的德国联邦公路研究研究所（Federal Highway Research Institute, BASt）在该高速公路旁设有两座测量集装箱，本次验证工作即依托该设施完成。本次作业测试了多种飞行剖面方案，研究结果显示，仅在以恒定速度实施垂直爬升的工况下，方可获得有效的空气质量测量结果。本次航次采集的测量数据已收录于本数据集中。
