Why Clarity for wildfire air pollution monitoring?

Rugged & Low Maintenance for Remote Deployment

Built for professional use outdoors, Clarity air quality sensors are weatherproof, durable, and require virtually no maintenance or manual calibration. Deploy them anywhere in minutes, without headaches — no downtime, just continuous data. Unlike hobby sensors that need frequent maintenance, our Node-S monitors are solar-powered and cellular-connected, so they keep reporting through smoke, heat, and dust during wildfire emergencies when power or WiFi infrastructure may fail.

EPA-Validated Accuracy for Wildfire Smoke

Clarity’s sensors use advanced calibration and QC to maintain accuracy even in extreme smoke conditions. While consumer sensors can overestimate pollution or vary device-to-device during wildfires, Clarity Nodes are expertly calibrated and field-validated by the EPA to meet performance targets during wildfire smoke events. We developed a specialized wildfire calibration model for the EPA FASM to ensure readings stay reliable even at very high AQI levels. With Clarity, you get actionable data you can trust when air quality reaches hazardous levels.

Modular Platform for Multi-Pollutant Insight

Clarity’s modular air monitoring platform goes beyond basic particle counts. The Node-S measures PM2.5 and NO2 and can be expanded with the Black Carbon, Ozone, Multi-Gas, and Wind Add-on Modules (see bundles below) to fully characterize wildfire smoke. Modules integrate seamlessly with the Node-S, giving you the flexibility to adapt your air monitoring network to changing air pollution conditions and get the complete picture of smoke impacts that consumer sensors can’t match.

Real-Time Air Pollution Data & Alerts

All Clarity data feeds into our cloud Dashboard in real time, with the option to share data publicly using a custom iteration of our OpenMap data sharing platform with your organization’s branding (free for a limited time!). WIth our our AQ Alarms and OpenMap email notification features, you can alert your community instantly when conditions worsen. No more waiting for hourly data from reference monitors — Clarity delivers up-to-the-moment data to inform decisions (school closures, public alerts, etc.).

Featured on EPA’s Fire & Smoke Map

In January 2025, as devastating wildfires struck Los Angeles, over 200 Clarity sensors across the LA metro were rapidly integrated into the EPA’s official Fire & Smoke Map. The EPA team fast-tracked Clarity’s inclusion because our data passed preliminary accuracy tests and dramatically improved coverage in smoke-impacted areas. Clarity is the only professional-grade air pollution sensor included on the Fire & Smoke Map. This EPA validation ensures that Clarity’s data meets rigorous standards during wildfire events.

Proven in Real-World Wildfire Response

Clarity has been battle-tested in major wildfire incidents, from Boulder, Colorado, to San Francisco, California. During the January 2025 Southern California wildfires, LAUSD’s Clarity network provided critical real-time PM2.5 readings and AQI updates as smoke choked the region. Emergency responders and the public relied on Clarity’s sensors to guide school closures, health warnings, and evacuation decisions — real-world proof of performance under pressure.

Wildfire monitoring packages: Limited time discounts!

To celebrate our inclusion on the Fire & Smoke Map, we’re offering discounted pricing on Clarity’s wildfire air quality monitoring solutions. These bundles combine our core Node-S air quality monitor with wildfire-specific Add-on Modules and software tools – everything you need to track smoke and protect your community.

Dust (PM10) Module

Highly accurate coarse particulate detection for dust and ash

Bigger particles like ash become major pollutants during and after wildfires. The Dust Module plugs into the Node-S to measure coarse particulate matter (PM₁₀) and total suspended particulates (TSP) in real time to provide reliable, high-resolution data on large particle pollution that standard smoke sensors can miss. With this module, you can effectively track and manage dust and ash impacts – even in remote, off-grid environments – thanks to seamless solar-powered, cellular Node-S integration. Available now for pilot testing! 

Use Case: A county air quality agency equips Node-S monitors with the Dust Module around a wildfire burn scar during cleanup efforts. This helps them detect harmful ash and dust particles being stirred up, allowing timely health advisories and protective measures for workers and returning residents.

Black Carbon Module

Distinguish wildfire smoke from other urban air pollution sources

Wildfire smoke isn’t just PM2.5 – it has a unique signature. Our Black Carbon Module identifies the sooty black carbon within particulate matter, using 5-wavelength optical analysis. This helps you tell apart biomass smoke vs. other pollution sources. For example, if haze is coming from a wildfire, black carbon levels will spike differently than if the haze were from local traffic.

Use Case: A regional air district can deploy the Black Carbon Module to confirm that elevated PM is due to wildfire smoke (rich in black carbon) and not an industrial source, informing appropriate health advisories.

Multi-Gas Module

Measure carbon monoxide & ozone to evaluate smoke chemistry

Wildfires don’t only create particles; they also emit gases that impact health. The Multi-Gas Module adds sensors for CO and O₃ (carbon monoxide and ozone) – two key pollutants during fires. CO is a direct tracer of wildfire smoke; high CO readings mean a fresh smoke plume is present (indicating danger even if particles are not visible). Ozone can surge on sunny days downwind of wildfires due to chemical reactions in the smoke. By monitoring both, you get a more complete picture of air quality.

Use Case: A school district can use the Multi-Gas add-on to know if outdoor CO is creeping up from nearby wildfires (a sign to keep an eye on indoor air quality), and if outdoor ozone is reaching levels that trigger asthma warnings

Wind & Met Module

Track wind speed & direction to better predict spread and improve forecasts

Understanding where smoke is coming from and where it’s heading is crucial in wildfire events. The Wind & Meteorological Module plugs into the Node-S to measure local wind speed and direction, plus environmental conditions. This lets you correlate pollution spikes with wind shifts – essentially pinpointing the source and trajectory of smoke.

Use Case: A tribal air program might deploy Wind Modules with their sensors around a reservation. When a wildfire ignites nearby, they can see that “smoke levels are rising at the east sensor when winds blow from the east” – confirming the fire’s impact and helping predict which communities will be hit next.

OpenMap Plus

Build a custom-branded, public-facing wildfire air quality map

During wildfire season, transparency and public information are vital. OpenMap Plus is our cloud software feature that lets you instantly publish your air pollution sensor readings to a public map or website with custom branding. In an emergency, you can share an easy link with residents so they see real-time air quality in their neighborhood (without needing to interpret complex data). OpenMap Plus also provides simple tools for community engagement – embed the map on your site, add briefing notes, and notify your constituents in real time with email alert subscriptions.

Use Case: A regional air district creates a public OpenMap page showing all its Clarity sensors, so during a wildfire, residents can zoom into their town and see current smoke levels and health messages. This builds trust and helps people make decisions (evacuate, stay indoors, etc.) based on live local data.

Clarity Sensing-as-a-Service Air Quality Monitoring Solutions

Trusted for real-world wildfire monitoring by air quality leaders

Don’t just take our word for it – leading organizations across North America are already using our air quality monitoring equipment to guard against wildfire smoke. Here are a few examples of how our customers have deployed Clarity for wildfire monitoring:

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."

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."

‍

Bill Hayes

Air Quality Program Coordinator, Boulder County Public Health

"After the Marshall fire we installed a total of 22 monitors in the burn area. The Node-S is solar powered, has impressive battery-life and transmits data via cellular network. That means we could put these monitors anywhere that the sun shines and that you can make a cell call."

‍

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.”

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."

Frequently Asked Questions

How does wildfire smoke impact air quality and public health?

Wildfire smoke contains high concentrations of PM₂.₅ that can cause serious respiratory and cardiovascular issues. Real-time air quality monitoring is essential to protect public health during wildfire events, enabling timely alerts, evacuations, and clean air interventions. Learn more in our Wildfire Smoke and Air Quality blog.

Can Clarity’s sensors detect and differentiate wildfire smoke from other pollutants?

Yes. Clarity sensors measure PM₂.₅ and other pollutants associated with wildfire smoke. Our wildfire-specific calibration model adjusts readings during smoke-heavy events, improving accuracy even in extreme pollution scenarios.

Why is it important to monitor air quality during wildfires?

During fires, air quality can change by the hour. Monitoring allows air quality agencies to issue targeted health warnings, protect vulnerable populations, and assess the effectiveness of response actions. Clarity’s solar-powered, cellular-connected sensors continue operating even when infrastructure fails.

What challenges do traditional air monitors face in wildfire scenarios?

Fixed monitors rely on electricity and internet, which often fail during wildfires. They’re also too sparse to detect hyperlocal variations. Clarity’s low-cost, resilient sensors fill critical gaps, providing reliable data when it’s needed most.

How do Clarity’s sensor networks help during wildfire smoke events?

Clarity’s solar-powered Node-S air quality sensors can be rapidly deployed and begin transmitting real-time data via cellular networks immediately.
