Commuter traffic feeding onto the A38 adds a further, consistent contribution to local readings. Syston sits within Leicestershire, and its air quality profile is driven mainly by road traffic and the density of the centre. The region's typical south-westerlies generally provide reasonable ventilation, keeping levels close to typical UK urban averages for a town this size.

When is air pollution at its worst in Syston?

You can roughly predict Syston's air quality just by knowing the time of year. Come winter, NO₂ and PM2.5 usually creep up, as heating and calmer air let A38 traffic emissions linger rather than disperse. Summer's more of a mixed bag: ozone can spike in strong sun, but overall dispersion tends to be better than the depths of winter. Spring and autumn don't usually cause much concern, sitting comfortably between winter's peak and summer's ozone spikes.

Are air quality levels in Syston 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.
