The latest in air quality monitoring

Transboundary air pollution spreads across borders, harming health and ecosystems. Global cooperation is key to identifying sources and reducing pollution worldwide.

Clarity’s Lab Team is excited to release version 2.1 of our PM2.5 Global Calibration! v2.1 improves upon the powerful v2 PM2.5 Global Calibration by increasing accuracy during high-pollution events. In this blog post, we explain how we developed this new calibration and share performance metrics that show a significant improvement in sensor accuracy, especially during periods with elevated pollutant concentrations.

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.
