Nitrogen dioxide Kiel, Bahnhofstr. Verk. 1-hour mean 2024

In order to protect people's health and vegetation from the influences of excessive air pollution, air quality is continuously examined and assessed in accordance with legal regulations. For this purpose, the State Office for the Environment (LfU) in Schleswig-Holstein operates a network of measuring stations at which air pollutants are measured using different methods. The measurement data from Schleswig-Holstein and much additional information on the measurements will be forwarded to the Federal Environment Agency and reported to the European Commission together with the data from all federal states. All currently published data are to be classified as ***provisional***, as they are automatically checked for validity for your quick information. Before the final assessment and assessment of the air quality, a multi-stage check according to legal requirements takes place later. For CSV files, the 3 o'clock measurement is ‘missing’ on the day of the changeover from normal time (CET) to daylight saving time (CEST), while on the day of the changeover from daylight saving time to daylight saving time there are two 3 o'clock measurements. The JSON files are not affected by this problem, here normal time is used throughout. [Information about the measuring station](https://www.schleswig-holstein.de/DE/Specialised content/L/air quality/measurement stations/KielBahnhofstr.html)为保障民众健康与植被免受过度空气污染侵害，需依据法定规范持续开展空气质量监测与评估工作。 为此，石勒苏益格-荷尔斯泰因州环境局（State Office for the Environment, LfU）搭建了空气质量监测站网络，采用多种检测方法对空气污染物进行测定。 石勒苏益格-荷尔斯泰因州的监测数据，以及大量与监测相关的补充信息，将被报送至德国联邦环境署，并与全德各联邦州的监测数据一并上报至欧洲委员会。 当前所有已公开发布的数据均归类为**临时数据**，因系统会自动完成有效性校验以快速提供参考信息。在最终完成空气质量评定与评估前，后续还将依据法定要求开展多阶段核查工作。 对于CSV格式文件，在标准时间（CET，Central European Time）切换至夏令时（CEST，Central European Summer Time）当日，凌晨3时的监测数据会出现缺失；而在夏令时切换回标准时间当日，则会出现两条凌晨3时的监测数据。JSON格式文件不受此问题影响，全程采用标准时间。 [监测站信息](https://www.schleswig-holstein.de/DE/Specialised content/L/air quality/measurement stations/KielBahnhofstr.html)
