Mount Vernon's air quality in New York reflects the lower Hudson Sound position in Westchester County adjacent to New York City's northern boundary, with vehicle emissions from I-87 and the surrounding dense urban residential character contributing local sources. The broader New York metropolitan area's regional ozone and PM2.5 on prevailing southwesterly winds consistently elevates background pollution, while Bronx River provides limited ventilation throughout the year.

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