BLUME, Berlin's air-quality measurement network, has tracked pollutants since 1975 and today runs about 15 automatic stations measuring NO2, particulate matter, ozone, carbon monoxide and more. Stations report to the central hub every five minutes, feeding an hourly air-quality index and real-time public data on luftdaten.berlin.de — downloadable as CSV or via a REST API under an open licence, and complemented by passive samplers and a dispersion model. The measurements underpin the city's clean-air plan (Luftreinhalteplan) and its low-emission zone.
