When is air pollution at its worst in Frimley?
Most of spring and autumn stays fairly steady, right in the middle of those two extremes. Frimley's air quality follows a familiar seasonal pattern most UK towns share. Come winter, NO₂ and PM2.5 usually creep up, as heating and calmer air let A2 traffic emissions linger rather than disperse. Summer brings a different issue — stronger sunlight can push up ozone levels on hot, sunny days, even though traffic pollution itself often disperses more easily.
Are air quality levels in Frimley 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.
