When is air pollution at its worst in Yeovil?
Ask a local in Yeovil and they'll tell you air quality changes noticeably from season to season. Winter mornings can be the trickiest, with cold, still conditions trapping M62 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 Yeovil 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.
