Clarity Movement Co. and OpenAQ partner to address a gap in air quality data availability around the world. Data from Clarity sensors around the world can now be integrated with OpenAQ to empower researchers, governments and communities in taking action against air pollution.

“The partnership between OpenAQ and Clarity brings together best-in-class partners offering promising possibilities for improving air quality in cities around the world,” said Ailun Yang, Bloomberg Philanthropies.

Clarity Movement Co. and OpenAQ today announced a partnership to address a gap in air quality data availability around the world. Available air quality data empowers governments and communities to take action against air pollution.

Starting today, data from participating Clarity sensors around the world now appears on the OpenAQ map. In addition, the data from Clarity sensors are available for use by OpenAQ for other analysis functions, and available to OpenAQ users.

“The partnership between OpenAQ and Clarity brings together best-in-class partners offering promising possibilities for improving air quality in cities around the world,” said Ailun Yang, who leads international initiatives for the environment program at Bloomberg Philanthropies. “By strengthening monitoring and increasing transparency and access to trusted sources of air quality data, we can effectively tackle air pollution with better designed and informed policies and solutions to protect communities and those most at risk.”

“Making data on air quality more transparent and accessible to all is a game changer in the fight against air pollution around the world,” explained Matt Whitney, portfolio manager, Clean Air Fund. “That’s why the Clean Air Fund supports OpenAQ’s enabling data platform and it’s great to see this new partnership with Clarity. We encourage other air quality sensor companies to follow suit in openly sharing their data for the benefit of all. Cleaning up our air is vital for our health, climate and economy.”

“OpenAQ is very excited about this data-sharing partnership with Clarity,” said Chisato Fukuda Calvert, Ph.D., deputy director, OpenAQ. “Clarity has been working actively with governments across the globe to help develop more robust air quality monitoring networks in communities that bear the biggest burden from air pollution. We hope that this partnership will help pave the way toward greater data transparency and encourage more companies to open up their data so that we can collectively advance the mission to fight air inequality across the globe.”

“Clarity is thrilled to make air quality data from our participating partners’ air monitoring networks available to the OpenAQ community,” said Sean Wihera, director of business development, Clarity Movement Co. “Our mission is to empower the world to fight air pollution with accurate air quality data at scale, and we’re thrilled to support the important work being done by OpenAQ in bringing air quality data to their vibrant ecosystem of researchers, activists and regulators. The availability of public, high-resolution air quality data can greatly improve regional air quality management coordination and research around the world!”

“We are thrilled that we are now able to share data from our network of Clarity air quality sensors in the City and County of Denver with the broader OpenAQ community,” said Michael Ogletree, Air Quality Program Manager, City and County of Denver. “Open access to air quality data is key to improving our collective understanding of air pollution and its impacts. Platforms like OpenAQ’s are essential to advancing air quality awareness and research initiatives. The addition of data from Clarity and other low-cost sensors will vastly expand the number of measurement points available to the OpenAQ community and help OpenAQ realize its mission of promoting equitable access to clean air around the world.”

Air pollution is responsible for as many as 1 in 5 premature deaths globally — yet in many regions around the world, a lack of reliable air quality data means that air pollution remains an invisible killer. Less than 50% of governments around the world have any air quality monitoring infrastructure in place, limiting the ability of governments and other stakeholders to take informed action to improve air quality.

Clarity provides air quality monitoring services to customers in more than 60 countries around the world — including many where reference monitors are limited or unavailable. While Clarity’s customers always retain all rights to the air quality data produced by their devices, they now have the option to share this information publicly with the OpenAQ community.

Some of the first Clarity customers to contribute data to the OpenAQ ecosystem include:

Brightline Defense in San Francisco, California
Watts Rising in Los Angeles, California
Groundwork Richmond in Richmond, California
Denver Department of Public Health & Environment (DDPHE) in Denver, Colorado
Love My Air Program in Denver, Colorado

Air quality data is sourced from the Clarity Node-S devices — Clarity’s flagship particulate matter (PM) and nitrogen dioxide (NO₂) sensor — in partners’ networks. Available measurements include Mass Concentration [μg/m3] and Number Concentration [#/cm3] for PM1, PM2.5, and PM10, and Concentration [ppb] for NO2. The OpenAQ community will have access to both raw data and data that has been calibrated via Clarity’s Remote Calibration service.
