Plymouth sits within Plymouth, and its air quality profile is driven mainly by road traffic and the density of the centre. Easterly winds offer a degree of natural ventilation, keeping pollution broadly in line with comparable UK towns. Rush-hour queues near the A14 are usually when readings climb the most.

When is air pollution at its worst in Plymouth?
Air quality in Plymouth isn't the same all year round — it really shifts with the seasons. Come summer, it's ozone rather than particulates that's the bigger concern, especially on still, sunny days. Through the colder months, readings near the A14 often rise, since chimney smoke and stagnant air stop pollutants clearing away. Most of spring and autumn stays fairly steady, right in the middle of those two extremes.
Are air quality levels in Plymouth 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.
