Ozone Lübeck, St. Jürgen 1-hour mean 2022

In order to protect people’s health and vegetation from the influences of high levels of air pollution, air quality is continuously examined and assessed according to legal regulations. For this purpose, the Land Office for Agriculture, 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 from there to the European Commission together with the data from all Länder. All currently published data must be classified as ***provisional***, as they are automatically checked for validity for your fast information. Before the final assessment and assessment of the air quality, a multi-stage test according to legal requirements takes place later. The CSV files “miss” on the day of the switch from normal time (CET) to summer time (CEST) the 3 o‘clock measurement, while on the day of the change 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 consistently used. [Information on the measuring station](https://www.schleswig-holstein.de/DE/Fachinhalte/L/luftqualitaet/Messstationen/LuebeckStJuergen.html)为保护民众健康与植被免受高浓度空气污染的损害，需依据法律法规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（Land Office for Agriculture, Environment and Rural Areas，LLUR）搭建了空气质量监测站网络，采用多种方法对空气污染物开展监测。 石勒苏益格-荷尔斯泰因州的监测数据及大量测量相关补充信息将报送至联邦环境署（Federal Environment Agency），随后由该机构联合德国其余联邦州的数据一同提交至欧盟委员会。 目前所有已发布的数据均归类为**临时数据**，因系统会自动进行有效性校验以快速提供信息。在最终开展空气质量评估与评级前，后续还需依据法定要求完成多阶段核验流程。 CSV文件存在夏令时切换异常问题：从标准时间（Central European Time，CET）切换至夏令时（Central European Summer Time，CEST）当日，会缺失3时的监测数据；而从夏令时切换回标准时间当日，则会出现两条3时的监测数据。JSON文件不受该问题影响，此类文件始终采用标准时间。 [监测站信息](https://www.schleswig-holstein.de/DE/Fachinhalte/L/luftqualitaet/Messstationen/LuebeckStJuergen.html)
