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.

为保护民众健康与植被免受过度空气污染的损害，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-荷尔斯泰因州环境局（State Office for the Environment, LfU）搭建了监测站网络，采用多种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上报至欧盟委员会。
目前所有已发布的数据均归类为**临时数据**，因仅为供快速参考而先完成初步有效性核查。后续将依据法定要求开展多阶段核验，之后方可完成空气质量的最终评估与判定。
在CSV文件中，当中欧标准时间（CET）切换至中欧夏令时（CEST）当日，3时的监测数据会缺失；而当中欧夏令时切换回中欧标准时间当日，则会出现两条3时监测数据。JSON文件不受此问题影响，全程采用中欧标准时间。
