When is air pollution at its worst in Warrington?

You can roughly predict Warrington's air quality just by knowing the time of year. Winter mornings can be the trickiest, with cold, still conditions trapping M25 traffic fumes and smoke from home fires close to the ground. Warmer months swap one problem for another — less smoke and heating pollution, but more ozone on the sunniest days. For much of spring and autumn, things settle into a fairly unremarkable middle ground.

Are air quality levels in Warrington 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.
