The nearby A47 corridor contributes steady vehicle emissions that affect roadside readings. Like much of Sefton, Crosby's air quality is shaped less by industry these days and more by everyday road traffic. Northwesterly winds off the coast help ventilate the town centre, keeping air quality at moderate levels typical for the region.

When is air pollution at its worst in Crosby?

Most of spring and autumn stays fairly steady, right in the middle of those two extremes. In Crosby, pollution levels don't stay flat — winter and summer look pretty different. In deep winter, a lack of wind lets A47 traffic fumes and woodsmoke settle instead of blowing through. 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 Crosby 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.
