Air readings for particulate matter — Daily values in Düsseldorf

The data set contains the daily values for particulate matter (PM 10 in µg/m³) from the urban measuring stations. In addition to the archive data for particulate matter, data on exceedance days and annual mean values are also available. Analogously, data sets for the load with nitrogen oxides are prepared. 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. Data on other pollutants are provided in data sets on benzene, ozone and soot. 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: Tag: Day of the week (Mon, Tue, Wed, Thu, Fr, Sat, Sun) Date: Date of measurement Loads: Values of the measuring station at Ludenberger Allee (measurements set at the end of 2013) Doro: Values of the measuring station on Dorotheenstraße Brinck: Values of the measuring station on Brinckmannstraße Aaper: Values of the measuring station in Aaper Wald (measurements set at the end of 2013) Data for PM10 in µg/m³本数据集收录来自城市空气质量监测站的颗粒物（particulate matter, PM₁₀，单位：微克/立方米）日度监测值。 除颗粒物存档监测数据外，本数据集还提供超标天数与年均值相关统计数据。 与之对应，本机构还制备了氮氧化物负荷相关数据集，其中包含存档时序数据、年均值以及最新实测值。含最新监测值的文件将通过另一套读取流程每小时自动更新一次。 城市监测站的地理空间信息数据收录于独立数据集之中。 其他污染物相关数据则分别归类于苯、臭氧与烟尘专项数据集内。 州首府杜塞尔多夫开展空气质量监测工作，并依据法定框架对监测结果进行评估，当前适用依据为《联邦排放保护法》（Federal Immission Protection Act）结合《第39号联邦排放保护条例》（39. Federal Immission Protection Regulation）。 更多相关信息可于环境署“空气质量”栏目页面查阅，其他信息源可通过“在线数据”页面的链接获取。 各数据文件包含以下字段信息： Tag：星期几（对应英文缩写Mon、Tue、Wed、Thu、Fr、Sat、Sun） Date：监测日期 Loads：卢登贝格大街（Ludenberger Allee）监测站的监测值（该站点监测工作始于2013年末） Doro：多罗特恩大街（Dorotheenstraße）监测站的监测值 Brinck：布林克曼大街（Brinckmannstraße）监测站的监测值 Aaper：阿珀森林（Aaper Wald）监测站的监测值（该站点监测工作始于2013年末） 数据单位：PM₁₀，微克/立方米
