Like much of London, City of, Soho's air quality is shaped less by industry these days and more by everyday road traffic. The prevailing Atlantic airflow help ventilate the town centre, keeping air quality at moderate levels typical for the region. The M1 generates consistent traffic-related NO₂ and PM2.5, particularly during peak commuting hours.

When is air pollution at its worst in Soho?
If you're tracking air quality in Soho, expect it to move around quite a bit through the year. 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. Once the heating goes on and the air turns still, pollution from the M1 and nearby chimneys tends to build up rather than clear. The shoulder seasons generally bring the mildest readings of the year.
Are air quality levels in Soho 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.
