Baltimore's Canton air quality reflects the southeast Baltimore waterfront neighbourhood, with vehicle traffic on the surrounding arterial corridors and the Canton Waterfront Park contributing local sources. The Patapsco River provides limited eastern ventilation, while the neighbourhood's residential character and the waterfront park generally maintain moderate Baltimore metropolitan readings and Canton generally tracks at typical inner southeast Baltimore neighbourhood levels throughout the year.

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.
