When is air pollution at its worst in Sevenoaks?
If you're tracking air quality in Sevenoaks, expect it to move around quite a bit through the year. 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. Winter mornings can be the trickiest, with cold, still conditions trapping A1 traffic fumes and smoke from home fires close to the ground. For much of spring and autumn, things settle into a fairly unremarkable middle ground.
Are air quality levels in Sevenoaks 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.
