Air readings — Locations of urban measuring stations

The data set contains the locations of the measurement stations of the city of Düsseldorf. The most up-to-date readings for nitrogen oxides from the urban measuring stations can be found in a data set, which is supplemented once per hour by readings for nitric oxide and nitrogen dioxide. The time series and the annual mean values for nitrogen oxides in Düsseldorf are stored in their own data sets, as well as data on the other pollutants benzene, ozone, soot and daily values for particulate matter. In addition to the archive data for particulate matter, data on exceedance days and annual mean values are also provided here. The state capital Düsseldorf performs air quality measurements and evaluates the results based on the legal basis. Currently, it is the Federal Immission Protection Act in combination with the 39. Federal Immission Protection Regulation. Further information can be found on the ‘Air quality’ page of the Environmental Agency. The values of the urban measuring stations on Dorotheenstraße and Brinckmannstraße are updated hourly. The following stations are operated by the city of Düsseldorf itself: Measuring point 701 — Ludenberger Straße 34-38 (measures discontinued at the end of 2013) Measuring point 709 — Dorotheenstraße 50-52 Measuring point 713 — Aaper Wald/Sailing airfield (measurements set at the end of 2013) Measuring point 714 — Brinckmannstraße 10 The files contain the following information: LATITUDE: Geographical width LONGITUDE: Geographical length ATTITUDE: Geographical altitude — here 0 GEOMETRY: Type of geoinformation — here Point NAME: Name of the measuring station ADDRESS: Street and house number in front of the station LEGAL VALUE: additional geoinformation HIGH VALUE: additional geoinformation
