Sharing code in the tech community hasn’t always been considered a virtue. But GitHub, with its easy interface and mammoth user base, has shown how allowing developers to build on one another’s software code can accelerate innovation of new projects and solve bugs with existing applications, all in a transparent, open-source code hosting platform. The air quality data space is ripe for this kind of move.
Opening access to air quality data
Today, in an effort to address this critical need, Environmental Defense Fund (EDF) is unlocking our new Air Quality Data Commons (AQDC), an open-access data platform where people can share and use data from low-and medium-cost air quality sensors. With the introduction of the AQDC, researchers now have access to more than the 60 million plus data points from EDF and our partners’ air pollution studies in Oakland, Houston and London.
Until recently, few outside of government could afford the expensive, specialized equipment needed to measure air pollution other than well-funded scientists, whose data was typically private until after the publication of a peer-reviewed paper. Even then, when they wanted to share their data with others in the field, they could do so only on an ad-hoc basis with limited infrastructure in place to support such collaboration.
Now, as scientists, cities and residents are taking advantage of new low-cost, high-quality sensors, and the amount of air quality data is growing rapidly, as is the need to store and share it. To unlock the benefits of the data for both scientists and society, it must be open and easily accessible.
Transparency drives innovation
Many of our academic partners have long expressed the desire to share their data — once they’ve had the opportunity to analyze it. However, they’ve lacked a platform that would allow them to do so. Similarly, donors are increasingly demanding that the data gleaned from the projects they’ve funded be available for others to use and explore. By building this community, we hope people will see a benefit to not only accessing available data but sharing their own — they can ask questions of fellow air quality scientists about trends they are seeing and learn from others who may have new was of analyzing existing data.
Our partner Karin Tuxen-Bettman, Program Manager for Google Earth Outreach sees value for cities and Google as well. “By adding to the Air Quality Data Commons, cities can feel confident their investments in air monitoring — whether through a fixed stationary network or city-owned vehicle fleets equipped with sensors — are creating enormous value,” she says. “Validated data shared on the AQDC will contribute to the larger database that Google’s Environmental Insights Explorer will pull from, enabling us to build hyperlocal air quality maps for more cities. By making this data available through a transparent process, the AQDC can accelerate action required to improve air quality.”
We look forward to growing this group of data scientists, companies and cities sharing and analyzing data into a robust community who will contribute to the scientific knowledge base, so we can better understand air pollution problems around the world.
The revolution of smaller, cheaper air pollution sensors has brought us here, but the full potential of this revolution will only be realized when a larger community of scientists, cities, residents and activists use the data we collect to take action and improve local air quality. Join us by downloading our data from the AQDC, or upload your own. We look forward to sharing and learning with you.
We are entering a new era of environmental innovation that is driving better alignment between technology and environmental goals — and results. #FourthWave
