When is air pollution at its worst in Sunningdale?
You can roughly predict Sunningdale's air quality just by knowing the time of year. Winter mornings can be the trickiest, with cold, still conditions trapping A26 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. Spring and autumn are typically the easiest months, air-quality-wise, for most residents.
Are air quality levels in Sunningdale 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.
