- Air pollution is often worse in the summer. Now, Chicago can monitor it neighborhood by neighborhood
Chicago has deployed 277 solar-powered air quality monitors across all wards, focusing on neighborhoods disproportionately affected by pollution. The network, part of the nation's largest community air quality monitoring system, provides real-time data, such as a safe air quality index of 31 recorded in Grant Park.
