Portland's Alberta Arts District air quality reflects the Northeast Portland creative neighbourhood, with vehicle traffic on Alberta Street and the surrounding mixed residential and arts character contributing local sources. Summer wildfire smoke from Oregon and Washington forests is an increasingly severe seasonal concern, while the neighbourhood's walkable character generally maintains moderate Portland metropolitan readings and the weekly Last Thursday art walk generates concentrated seasonal pedestrian and vehicle activity.

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.
