The nearby M11 corridor contributes steady vehicle emissions that affect roadside readings. Like much of Lincolnshire, Grantham's air quality is shaped less by industry these days and more by everyday road traffic. 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 Grantham?
Spring and autumn are typically the easiest months, air-quality-wise, for most residents. Here's the thing about Grantham: air quality has a clear seasonal rhythm. Once the heating goes on and the air turns still, pollution from the M11 and nearby chimneys tends to build up rather than clear. Summer brings a different issue — stronger sunlight can push up ozone levels on hot, sunny days, even though traffic pollution itself often disperses more easily.
Are air quality levels in Grantham 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.
