IMPROVING AIR QUALITY through collaboration and community partnerships
OpenAQ fights air inequality through open data, open-source tools, and a global, collaborative grassroots community.
Our mission is to enable previously impossible science, impact policy and empower the public to fight air pollution through open data, open-source tools, and cooperation.
We aggregate physical air quality data from public data sources provided by government, research-grade and other sources. These awesome groups do the hard work of measuring these data and publicly sharing them, and our community makes them more universally-accessible to both humans and machines.
