Denver's Washington Park air quality benefits from the 155-acre South Denver greenspace, with the park's mature elm and cottonwood canopy providing natural filtration. Vehicle traffic on South Downing Street and the surrounding affluent residential character contribute modest local sources, while the Rocky Mountain westerly airflows provide clean background ventilation on most days and Washington Park generally maintains among Denver's more moderately ventilated residential neighbourhood parks 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.
