Particulate matter (PM10) Flensburg 1-hour average 2022

In order to protect people’s health and vegetation from the influences of excessive air pollution, air quality is continuously examined and assessed according to legal regulations. For this purpose, the State Office for Agriculture, the Environment and Rural Areas (LLUR) 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 many additional information on the measurements are forwarded to the Federal Environment Agency and reported to the European Commission together with the data of all federal states. All currently published data must be classified as ***provisional***, as they are first checked for validity for your quick information. Before the final assessment and assessment of air quality, a multi-stage inspection according to legal requirements will take place later. In the CSV files, on the day of the change from normal time (CET) to daylight saving time (CEST) the 3 o‘clock measurement is missing, but on the day of the conversion from summer to normal time, there are two 3 o’clock measurements. The JSON files are not affected by this problem, here normal time is used throughout. [Information on the measuring station](https://www.schleswig-holstein.de/DE/Fachinhalte/L/luftqualitaet/Messstationen/Flensburg.html)为保护民众健康与植被免受过度空气污染影响，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-荷尔斯泰因州农业、环境与农村事务局（LLUR）搭建了空气质量监测站网络，采用多种方法对大气污染物进行监测。 石勒苏益格-荷尔斯泰因州的监测数据及大量监测相关附加信息，均报送至德国联邦环境署，并与全联邦各州的监测数据一同提交至欧洲委员会。 当前所有已发布的数据均归类为**临时数据**——由于这些数据是为快速向相关方提供信息而先行发布，仅完成了初步的有效性核验。后续将依据法定要求开展多阶段核查，待核查完成后，方可开展空气质量的最终评价与评估工作。 在CSV文件中，当标准时间（CET，Central European Time）切换为夏令时（CEST，Central European Summer Time）当日，3时的监测数据会缺失；而当夏令时切换回标准时间当日，则会存在两条3时的监测数据。JSON文件不受此问题影响，全程采用标准时间。 [监测站相关信息](https://www.schleswig-holstein.de/DE/Fachinhalte/L/luftqualitaet/Messstationen/Flensburg.html)
