Chatham's position in Medway means air quality is mostly determined by local road traffic and the compact scale of the centre. Easterly winds tend to disperse pollutants reasonably well, keeping readings close to typical UK small-town levels. The M40 sees the heaviest traffic, and that shows up clearly in local roadside monitoring.

When is air pollution at its worst in Chatham?
Chatham's air quality follows a familiar seasonal pattern most UK towns share. Winter mornings can be the trickiest, with cold, still conditions trapping M40 traffic fumes and smoke from home fires close to the ground. By summer, ozone tends to rise on bright days, while better ventilation generally keeps particulate and NO₂ levels lower than winter. For much of spring and autumn, things settle into a fairly unremarkable middle ground.
Are air quality levels in Chatham 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.
