When is air pollution at its worst in Cambridge?
In Cambridge, pollution levels don't stay flat — winter and summer look pretty different. In deep winter, a lack of wind lets A46 traffic fumes and woodsmoke settle instead of blowing through. Summer sunshine can drive up ozone locally, though overall air generally moves and clears more freely than in winter. Spring and autumn don't usually cause much concern, sitting comfortably between winter's peak and summer's ozone spikes.
Are air quality levels in Cambridge 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.
