Air readings for ozone — exceedances of limit values in Düsseldorf

The data set contains information on the exceedances of ozone limit values in Düsseldorf. The values are given in µg/m³. Data on other pollutants are provided in data sets on benzene and soot. In addition to the archive data for particulate matter (daily values for particulate matter), data on exceedance days and annual mean values for particulate matter are available. Similarly, the load is prepared with nitrogen oxides. Here you will find the time series as archive data, the annual averages and also the most up-to-date measured values. The files with the most up-to-date values are automatically added once an hour by another reading. The geoinformation of the urban measuring stations is available in a separate dataset. 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. Additional information can be found on the ‘Air Quality’ page of the Environmental Agency. Further information sources can be accessed via the links of the ‘Online Data’ page. The files contain the following column information: Year: 2003 to 2013 Number of 1h value over 180: Number of exceedances with an hourly value exceeding 180 µg/m³ Number of 8h value over 120: Number of exceedances with an 8-hour value above 120 µg/m³ Number of days with 8h value over 120: Number of exceedance days with an 8-hour value above 120 µg/m³ The measuring station was decommissioned in 2013.
