Madrid's Integral Air Quality System (Sistema Integral de la Calidad del Aire) runs 24 automatic stations measuring NO2, particulates and ozone across the city, 24/7. Readings update roughly every 20 minutes and are published as open data on datos.madrid.es. The same stations trigger the city's high-pollution episode protocol, whose alert levels impose M-30 traffic bans and 70 km/h speed limits.
