Emissions along the A40 represent the town's main traffic-related pollution source. Like much of Neath Port Talbot, Neath's air quality is shaped less by industry these days and more by everyday road traffic. Prevailing westerlies do most of the work keeping things in check, more so than any local policy or infrastructure change.

When is air pollution at its worst in Neath?
In Neath, pollution levels don't stay flat — winter and summer look pretty different. Warmer months swap one problem for another — less smoke and heating pollution, but more ozone on the sunniest days. In deep winter, a lack of wind lets A40 traffic fumes and woodsmoke settle instead of blowing through. Spring and autumn usually sit somewhere in between, so it's really the extremes of the year worth watching.
Are air quality levels in Neath 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.
