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Outdated regulatory standards don’t fit current trends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

Royal Automobile Club of Western Australia

Report: Monitoring Black Carbon 12-Month Summary

“The Black Carbon Module data provides RAC additional visibility into black carbon emissions. This information complements the PM2.5 data by providing a more detailed picture of vehicle-related pollution, supporting RAC’s advocacy, air-quality insights, and understanding of emissions impacts.”

David Broadhag

Technical Lead, Mobility and Sustainability Projects, Royal Automobile Club of Western Australia

“What we are expecting from the Black Carbon Module is three things. First is to evaluate black carbon concentration levels in Perth. Second, currently there’s no regulation in Australia for black carbon, so the outcomes of our study could potentially lead us to advocate on this matter. And last but not least, if we identify that we have a black carbon issue in Perth, this module will allow us to know its source: is it coming from traffic emissions, is it coming from biomass? That will help us diagnose the problem, and so find what the best solutions to fix it could be.”

Supervising Air Monitoring Specialist, Monterey Bay Air Resources District

"Clarity works very nicely for our wildfire air monitoring network. Their Node-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.”

“We're a nonprofit, so we don't have a ton of capacity to mess around with tech. Clarity Node-S 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.”

“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.”

"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."

Frequently Asked Questions

Clarity’s solution complements regulatory monitoring by filling spatial data gaps with a dense, high-resolution network of calibrated sensors. Our Node-S air quality monitoring devices and Add-On Modules offer measurements of key pollutants like PM₂.₅, NO₂, O₃, and black carbon, enabling agencies to track pollution trends in underserved or high-risk areas. Clarity also supports collocation and calibration with reference monitors to ensure data is reliable for supplemental monitoring applications.

Clarity’s data is ideal for non-regulatory supplemental monitoring (NSIM), community exposure assessments, and environmental justice reporting. While not a direct substitute for FRM/FEM instruments, Clarity’s FEM Ozone Module is EPA-designated, and our Node-S air quality sensor has been accepted for use on the EPA Fire & Smoke Map, demonstrating the reliability of our calibrated sensor data for government use.

Accuracy is maintained through a combination of global and local calibration models, continuous QA/QC, and performance benchmarking. Clarity sensors are regularly collocated with regulatory monitors during deployment to validate performance. We also offer Add-On Services like calibration reviews, accuracy reporting, and data validation to support decision-grade measurements.

Yes. Clarity’s cloud-based platform includes a robust, open API that allows agencies to integrate air quality data into internal dashboards, GIS platforms, or public portals. Many government users have successfully connected Clarity data to ArcGIS, Open Data platforms, and third-party health dashboards.

Absolutely. The plug-and-play nature of Clarity’s sensors—solar-powered, cellular-connected, and modular—makes it easy to scale deployments citywide or regionally. For example, Breathe London deployed 135+ sensors across the city to monitor pollution in neighborhoods, around schools, and near transportation corridors.

Clarity provides comprehensive support through our Project Support Services, including assistance with sensor siting, deployment, data QA/QC, stakeholder reporting, and regulatory engagement. Government partners also have access to onboarding, training, and ongoing technical support from our expert air quality team.

Clarity’s modular platform supports the monitoring of PM₂.₅, PM₁₀, NO₂, O₃, black carbon, and a range of gases via the Multi-Gas Module, including CO and VOCs. This flexibility allows agencies to tailor deployments to local air quality priorities—from traffic emissions to wildfire smoke or industrial pollutants.

Environmental agencies use real-time sensor data from Clarity to trigger public alerts, shape pollution mitigation policies, and prioritize health interventions in high-risk communities. Tools like Air Quality Alarms and OpenMap provide actionable insights that help public health departments and emergency responders protect vulnerable populations during events like wildfires, dust storms, or high-traffic days.
