The first systematic measurements of air quality began in Zurich in the early 1980s, which is why we can look back on one of the longest data series in Switzerland. The data from the measuring stations are made available on the Internet via the OpenData portal .

Further information and data on air quality measurement in the city of Zurich can be found here.
