The air quality picture in Kensington reflects a typical Kensington and Chelsea town, with traffic emissions and local commercial activity as key contributors. Commuter traffic feeding onto the A34 adds a further, consistent contribution to local readings. Shifting coastal winds usually ensure decent dispersal, so levels generally stay within the moderate range typical of UK towns.

When is air pollution at its worst in Kensington?
You can roughly predict Kensington's air quality just by knowing the time of year. Once the heating goes on and the air turns still, pollution from the A34 and nearby chimneys tends to build up rather than clear. Come summer, it's ozone rather than particulates that's the bigger concern, especially on still, sunny days. Spring and autumn are typically the easiest months, air-quality-wise, for most residents.
Are air quality levels in Kensington 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.
