When is air pollution at its worst in Widnes?
In Widnes, pollution levels don't stay flat — winter and summer look pretty different. Warmer months swap one problem for another — less smoke and heating pollution, but more ozone on the sunniest days. The coldest months usually bring the worst readings, as heating and temperature inversions keep A26 emissions from dispersing normally. For much of spring and autumn, things settle into a fairly unremarkable middle ground.
Are air quality levels in Widnes 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.
