The latest in air quality monitoring

The global NO₂ model offers a practical and scalable solution for indicative monitoring by applying a machine-learning-based correction to all Clarity Nodes, especially in regions where traditional reference equipment may not be available. In this post, we’ll walk you through how we built the model, how it performs, and how it can support your air quality initiatives.

London’s air pollution, once marked by dense and hazardous fog, has improved significantly through legislation and initiatives such as Breathe London.

Natural sources such as wildfires, volcanoes, and sandstorms emit air pollutants like particulate matter, nitrogen oxides, and volatile organic compounds, sometimes affecting human health and the climate.

Nitrogen oxides (NOₓ) are a group of pollutants formed from nitrogen and oxygen, primarily referring to nitric oxide (NO) and nitrogen dioxide (NO₂). These gases have adverse health effects and contribute to smog, acid rain, and ozone formation.

Carbon Monoxide, formed by the incomplete burning of carbon-based fuels, is invisible, odorless, and poisonous. It contributes indirectly to climate change and is regulated globally.

Clarity's latest advancements include the Multi-Gas and Dust Modules, Automated QC, additional Add-On Services, and an enhanced OpenMap public data sharing platform. These innovations empower organizations to collect, analyze, and share reliable air quality data.

Air quality has improved significantly since the LA fires began, and regular activities can be resumed. Yet, ash should be cleaned up by professionals and precautions may need to be taken near burn areas. Some toxic air pollutants may linger.

Air pollution poses a severe global health and environmental threat, making accurate and open air quality data crucial. Yet, many governments do not monitor or share air quality measurements, largely due to a lack of funding and technical expertise.

At Clarity, we’ve heard your feedback: organizations need an easy, impactful way to share real-time air quality data with communities and stakeholders. Whether it’s about protecting public health, raising awareness, or building trust, data-sharing should be simple and effective. That’s why we’re thrilled to announce our new and improved OpenMap, our revamped platform designed to turn your air pollution measurement data into actionable air quality awareness and insights — without the need for costly or complex third-party solutions.

Clarity Movement was founded in 2014; this year, 2024, marked ten years of our work empowering communities, governments, and industries to combat air pollution. Founded on the belief that clean air is a fundamental human right, we’ve grown from developing OPC sensor technology to deploying air quality sensors in more than 10,000 unique locations across 85+ countries. This blog reflects on our journey, highlights our milestones and partnerships, and outlines our vision for the future.
