Manchester's air quality in New Hampshire reflects its position in the Merrimack River valley, with vehicle emissions from the Everett Turnpike and the surrounding technology and manufacturing corridor contributing local sources in New England's largest city. The surrounding New Hampshire hills provide modest topographic variation, while the broader New England regional airshed contributes limited upwind pollution and the Merrimack valley's southerly orientation channels clean Canadian Arctic air on northerly wind days, generally maintaining moderate air quality conditions.

Coastal sea breezes can offer some relief from inland summer ozone buildup.
Are air quality levels in Manchester 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.
