Münster Air Quality Index (current and historical)

<p>The air quality index is determined at two measuring stations in Münster. It is calculated from the measured concentrations of the pollutants nitrogen dioxide, particulate matter (PM10 and PM2.5) and ozone.</p> <p>This dataset contains the positions of the measuring stations, the measured pollutant values and the air quality index calculated from them. You can find out how the index is calculated in the <a href="https://www.umweltbundesamt.de/calculation basis air quality index" target="_blank">Description at the Federal Environment Agency</a>.</p> <p>Values contained in the data files:</p> <ul> <li>Nitrogen dioxide (NO2) - Hourly mean in μg/m3 </li> <li>Particulate matter (PM10) - Daily moving average in μg/m3 </li> <li>fine particulate matter (PM2.5) - hourly daily moving average in μg/m3 </li> <li>Ozone (O3) - Hourly mean in μg/m3</li> <li>Air quality index in five gradations: very good, good, moderate, bad, very bad</li> </ul> <p>Locations of measuring stations:</p> <ul> <li>Station DENW095 - Ludwig Erhard Berufskolleg, Münster-Geist - "urban background" - Coordinates: 51.9365217168, 7.61158680053</li> <li>Station DENW260 - Münster Weseler Straße - "urban traffic" - Coordinates: 51.9532732608, 7.61937876070</li> </ul> <p>Further information can be found at the following links:</p> <ul> <li><a href="https://www.umweltbundesamt.de/daten/luft/luftdaten/luftqualitaet/eJzrWJSSuMrIwMhE18Bc18BoUUnmQstFeakLFhWXLDE0NDFYnOJWBJU30zUyXZwSko-sPLeKd1FuctPinMSS0w6eP68fnvY4enFOXvppB7mStXcZGBgBpZok0g==">Map of the two stations in Münster at the Federal Environment Agency</a></li> <li><a href="https://www.umweltbundesamt.de/daten/luft/luftdaten">General website: "Air data" at the Federal Environment Agency</a></li> <li><a href="https://inspire-geoportal.ec.europa.eu/srv/all/catalog.search#/metadata/e24015cb-64b6-4d14-bbcd-fdc829feb201">Validated dataset for the whole of Germany on the Inspire Geoportal</a></li> </ul> <p>According to Inspire Geoportal, these data are under the "Data License Germany 2.0 - Attribution".
