Like much of Hammersmith and Fulham, Hammersmith's air quality is shaped less by industry these days and more by everyday road traffic. Inland breezes from the surrounding countryside generally provide reasonable ventilation, keeping levels close to typical UK urban averages for a town this size. Commuter traffic feeding onto the A34 adds a further, consistent contribution to local readings.

When is air pollution at its worst in Hammersmith?
In Hammersmith, pollution levels don't stay flat — winter and summer look pretty different. Once the heating goes on and the air turns still, pollution from the A34 and nearby chimneys tends to build up rather than clear. Summer sunshine can drive up ozone locally, though overall air generally moves and clears more freely than in winter. Spring and autumn tend to be the calmer, more moderate stretches by comparison.
Are air quality levels in Hammersmith 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.
