Particulate matter (PM2.5) Itzehoe 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.
