Once the heating goes on and the air turns still, pollution from the A483 and nearby chimneys tends to build up rather than clear. By summer, ozone tends to rise on bright days, while better ventilation generally keeps particulate and NO₂ levels lower than winter.
Are air quality levels in Market Harborough 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.
