Cities such as London, Paris, and Perth have worked with Clarity to implement hybrid, low-cost ambient air quality monitoring networks to supplement existing regulatory air pollution measurement networks.

  • Air sensors are increasingly recognized as a valuable tool for indicative and non-regulatory supplemental and informational monitoring (NSIM). 
  • Clarity’s Sensing-as-a-Service solutions are designed to complement existing government infrastructure.
  • We work with you to design a robust air quality monitoring network that is validated for data accuracy and precision.

Proven success with air monitoring

Clarity Case Study

Breathe London

The Breathe London Community Sensing Network, the largest air quality sensing network in the world, aims to democratise air quality monitoring and create a community of groups who support each other and share their experiences and ideas for improving air pollution conditions. Learn more >>

Modernize your air quality monitoring infrastructure to address current air pollution issues

There is an increasing demand for high-resolution, accurate air pollution data.

Increased public awareness of air pollution issues

Communities around the world are creating increased public accountability for air quality managers.

Limited budgets for air monitoring equipment

Annual federal funding for U.S. state and local air quality management grants has decreased by 20% since 2004 after adjusting for inflation.

Expensive reference equipment leads to blind spots

Federal reference monitors (FRM) are designed to monitor air quality trends year-over-year — but can’t identify day-to-day, localized pollution events.

Outdated regulatory standards don’t fit current trends

Many air quality regulations are decades old and do not adequately address modern-day air pollution challenges.

Are air quality sensors accurate?

To support a broader understanding and more effective use of this technology, the US EPA recently released performance standards for air sensors that will help to better characterize the performance of commercially available air sensors in a clear and standardized way.

Air quality monitoring success stories

Michael Ogletree

Air Quality Technical Services Program Manager

“Addressing community concerns and improving public health are the primary goals of any air quality program. The Clarity Nodes we have deployed are placed near sensitive populations and projects as a way of better protecting the health of our residents and better informing our decisions around air quality.”

William Chevalier

Supervising Air Monitoring Specialist

"We wanted a network that would get real-time data out to the public immediately and show air quality changes in real-time — which we had been unable to do with our network of reference-grade equipment alone."
