Like much of Ealing, Ealing's air quality is shaped less by industry these days and more by everyday road traffic. Moist Atlantic fronts do most of the work keeping things in check, more so than any local policy or infrastructure change. The M74 sees the heaviest traffic, and that shows up clearly in local roadside monitoring.

When is air pollution at its worst in Ealing?
There's a clear yearly cycle to air quality in Ealing if you look closely. Come winter, NO₂ and PM2.5 usually creep up, as heating and calmer air let M74 traffic emissions linger rather than disperse. Summer sunshine can drive up ozone locally, though overall air generally moves and clears more freely than in winter. Most of spring and autumn stays fairly steady, right in the middle of those two extremes.
Are air quality levels in Ealing based on measurements or forecasts?
It is forecasts derived by downscaling forecasts provided by EU’s Copernicus Atmosphere Monitoring Service (CAMS) by taking into account local conditions such as traffic patterns. CAMS bases its forecast on satellite measurements of particles and chemical compounds in the atmosphere. Airmine’s services were developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team.
