The network dates to 1995, when one monitor covered the whole city; it now runs 27 fixed stations and one mobile. PM2.5 was only added in 2017, and a separate national network supplies the rest of the picture.

The strongest source is the operator's or the city's own reporting — an official report, dataset or press release. It grades who did the looking — not how well the project went.

İstanbul Büyükşehir Belediyesi (İBB) runs Istanbul's oldest air-quality network — dating to 1995, when it was the city's sole monitor — now spanning 27 fixed and one mobile station measuring SO2, NO2, CO, O3, PM10 and, since 2017, PM2.5. Hourly readings are published in real time on İBB's public portal and the İBB CepHava app, on a platform İBB says its own engineers built. The national Ministry of Environment operates roughly a dozen additional Marmara Clean Air stations in the city, so the full picture combines both networks.
