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.

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Outdated regulatory standards don’t fit current trends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

Jyrgalbek Shamyraliev

Vice-Mayor, Bishkek City Mayor’s Office

"The data provided by the sensors helped to speed up the city’s decision-making. Today, the sensor readings have had a direct impact on public opinion. This year, we launched public ecological transport and eco-taxi, and we are launching a new system of dedicated public transport lanes that will directly affect the transition to eco-friendly modes of transportation.”

Bolat Amirgaliyev

Head of Environment Division, EcoAlmaty

"Today we have 50 Clarity sensors in Almaty that provide us with online data on the type of particles and pollution in different parts of the city. Thanks to these sensors, we can plan environmental measures in Almaty.”

Begaim Alipova

Head of Atmospheric Pollution Observation Division, Kyrgyzhydromet

"In 2020, we installed 50 sensors in the city of Bishkek. Since the Clarity Node-S sensors installed in Bishkek are small, we installed them all over the city. We placed some of them near roads, some in residential areas, and some in social facilities. Thanks to the Global SIM Card which is incorporated in the sensors, we get the data directly to our system which allows us to visualize the data. The data is ready for analysis.”

Richard Stedman

Air Pollution Control Officer at the Monterey Bay Air Resources District

"We don’t have a lot of staff time to spend setting up or fine-tuning this equipment — Clarity’s managed service model allows us to multiply the number of sensors in our network with minimal additional overhead on our end. We're going from six particulate matter monitors to more than 20 — with one placed in each local municipality — so we expect to have more granularity in looking at how smoke impacts people across our three-county jurisdiction."

Dr. Ian Longley

Principal Scientist - Air Quality, National Institute of Water and Atmospheric Research

"We needed high-density data to develop a model that was representative of a real situation on a very local scale – so multiple devices and multiple locations. The Clarity Node-S was ideal for this use case."

William Chevalier

Supervising Air Monitoring Specialist, Monterey Bay Air Resources District

"We are very happy with the Dashboard — it makes it very easy to access and review data from our network."

Michael Ogletree

Air Quality Technical Services Program Manager at the DDPHE

"Clarity provided an off-the-shelf solution that was easy to deploy. Clarity Nodes are easy to set up and after reviewing a co-location we had in place, the data was in line with our expectations. The flexibility in changing the data capture rate was key — I was able to remotely configure the nodes to collect data at a higher or lower resolution as needed."

Janice Lam Snyder

Representative, Sac Metro Air District

"A program is only half the program when you have the data, and the other half is what information the community will have so that they know what actions to take to protect themselves, to protect their family, their employees, and just their community members in general."

David Frisbey

Planning and Air Monitoring Manager, Monterey Bay Air Resources District

"The best thing I can say about Clarity is the reduction of effort by our air monitoring staff. Very little hands-on work is required to operate the equipment, which from a management standpoint is a real benefit to the District. It's implemented quickly, we can start streaming the data immediately, and we really don't have to do much more than that.”

Eddie Ahn

Executive Director, Brightline Defense

"Clarity was our first-choice air quality monitoring provider for several reasons. We enjoyed working with the Clarity team - they are highly knowledgeable and always responsive. The Node-S devices themselves are also incredibly resilient, which was especially important for us when deploying the monitors in emergency conditions during the wildfire events this past year."

William Chevalier

Supervising Air Monitoring Specialist, Monterey Bay Air Resources District

"We were excited when we saw what Clarity was offering — it works very nicely for our objectives with the wildfire air monitoring network. We liked that Clarity’s sensors are very quick to install and very easy to use, thanks to the native solar panel and cellular antenna. Not having to use somebody else's WiFI in a remote location is great — that had been a major issue for us with several projects.”

Adrian Rehn

Project Leader, Valley Vision

“We're a nonprofit, so we don't have a ton of capacity to mess around with tech. Clarity devices are easy to deploy and solar-powered, so you can put them in parks, on rooftops, wherever — and they just work. We can focus on working with our community members.”

Michael Ogletree

Air Quality Technical Services Program Manager, Denver Department of Public Health and Environment

“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, Monterey Bay Air Resources District

"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."
