March's position in Cambridgeshire means air quality is mostly determined by local road traffic and the compact scale of the centre. Rush-hour queues near the M8 are usually when readings climb the most. Moist Atlantic fronts help ventilate the town centre, keeping air quality at moderate levels typical for the region.

When is air pollution at its worst in March?
March's air quality follows a familiar seasonal pattern most UK towns share. The coldest months usually bring the worst readings, as heating and temperature inversions keep M8 emissions from dispersing normally. By summer, ozone tends to rise on bright days, while better ventilation generally keeps particulate and NO₂ levels lower than winter. The shoulder seasons generally bring the mildest readings of the year.
Are air quality levels in March 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.
