Nitrogen Dioxide

Air pollution disrupts sleep. Poor air quality affects respiratory health and the central nervous system, while global warming’s nighttime warmth additionally interferes with the body’s circadian thermoregulation.

In San Francisco, New York, and London, public transportation lowers greenhouse gases and other pollutants, improving urban air quality and supporting public health.

Air pollution has changed over time, with sources evolving from wood burning and smelting to widespread fossil fuel use, industrial emissions, and intensified wildfires.

LA battles air pollution driven by geography, traffic, and summer heat. Learn about its smog history, current challenges, and efforts to protect public health.

Air pollutants influence ecosystems, the water cycle, and global temperatures by driving acid rain, ocean acidification, ozone depletion, the greenhouse effect, and changes in Earth's albedo.

Smog includes two main types: sulfurous smog, linked to coal burning and sulfur dioxide, and photochemical smog, formed by sunlight-driven reactions between nitrogen oxides and VOCs, producing ozone and particulate matter.

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.

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.

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.
