The aqicn.org project is a non-governmental project started in 2007 and is based in Beijing, China. The group’s mission is to promote air pollution awareness and provide a unified air quality information source for the whole world, in real-time. The aqicn.org map uses georss feeds to display the location of air quality sensors in a Google map, labeled with the air quality index number at each site, and color-coded according to whether or not the air quality index score is considered hazardous, very unhealthy, unhealthy, unhealthy for sensitive groups, moderate, and good, by city. In real time. Visit the map!
