When is air pollution at its worst in Northampton?
In Northampton, pollution levels don't stay flat — winter and summer look pretty different. Summer's more of a mixed bag: ozone can spike in strong sun, but overall dispersion tends to be better than the depths of winter. In deep winter, a lack of wind lets A303 traffic fumes and woodsmoke settle instead of blowing through. Most of spring and autumn stays fairly steady, right in the middle of those two extremes.
Are air quality levels in Northampton 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.
