Ozone Itzehoe 1-Hour Average 2023

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 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 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/ItzehoeOelixdorfer.html)为保护民众健康与植被免受过度空气污染的危害，需依据法定规范对空气质量开展持续性监测与评估。 为此，石勒苏益格-荷尔斯泰因州环境局（State Office for the Environment，LfU）搭建了空气污染物监测站网络，站内采用多种技术手段开展污染物监测工作。 石勒苏益格-荷尔斯泰因州的监测数据及大量相关测量补充信息，将被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。 所有当前已发布的数据均归类为**临时（provisional）**数据，因仅完成初步有效性核验以快速提供信息。后续还需依照法定要求开展多阶段核查，方可进行空气质量的最终评估与判定。 在CSV格式文件中，当从标准时间（CET）切换至夏令时（CEST）的当日，3点的监测数据会出现缺失；而在夏令时切换回标准时间的当日，则会存在两条3点的监测数据。JSON格式文件不受此问题影响，全程采用标准时间进行记录。 [监测站详情](https://www.schleswig-holstein.de/DE/Fachinhalte/L/luftqualitaet/Messstationen/ItzehoeOelixdorfer.html)
