Come winter, NO₂ and PM2.5 usually creep up, as heating and calmer air let M8 traffic emissions linger rather than disperse. Spring and autumn tend to be the calmer, more moderate stretches by comparison.

Are air quality levels in Weybridge 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.
