When is air pollution at its worst in Worcester?
Spring and autumn don't usually cause much concern, sitting comfortably between winter's peak and summer's ozone spikes. Ask a local in Worcester and they'll tell you air quality changes noticeably from season to season. Come winter, NO₂ and PM2.5 usually creep up, as heating and calmer air let A2 traffic emissions linger rather than disperse. By summer, ozone tends to rise on bright days, while better ventilation generally keeps particulate and NO₂ levels lower than winter.
Are air quality levels in Worcester 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.
