When is air pollution at its worst in Surrey?
Air quality in Surrey shifts noticeably across the seasons, shaped by its sprawling suburban streets in the Fraser Valley. Winter rain keeps the air generally clean, while hot, still summer days can trap traffic emissions and wildfire smoke against the surrounding mountains. Its position within the Fraser Valley air basin means smog can linger longer than on the open coast.
Are air quality levels in Surrey 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.
