Boston's position in Lincolnshire means air quality is mostly determined by local road traffic and the compact scale of the centre. The M74 sees the heaviest traffic, and that shows up clearly in local roadside monitoring. Southwesterly winds usually ensure decent dispersal, so levels generally stay within the moderate range typical of UK towns.

When is air pollution at its worst in Boston?
If you're tracking air quality in Boston, expect it to move around quite a bit through the year. By summer, ozone tends to rise on bright days, while better ventilation generally keeps particulate and NO₂ levels lower than winter. Winter mornings can be the trickiest, with cold, still conditions trapping M74 traffic fumes and smoke from home fires close to the ground. The shoulder seasons generally bring the mildest readings of the year.
Are air quality levels in Boston 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.
