When is air pollution at its worst in Northwich?
For much of spring and autumn, things settle into a fairly unremarkable middle ground. Seasons make a real difference to air quality in Northwich, more than most people realise. Winter mornings can be the trickiest, with cold, still conditions trapping M5 traffic fumes and smoke from home fires close to the ground. Summer brings a different issue — stronger sunlight can push up ozone levels on hot, sunny days, even though traffic pollution itself often disperses more easily.
Are air quality levels in Northwich 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.
