Map air quality in your city

Understanding when and where air pollution’s impacts are felt within your city, as well as which pollutants contribute most to poor air quality, allows you to better target interventions and maximize their impact.

Air quality data is available from several sources, including regulatory monitors, low-cost air sensors, satellite retrievals and models. This section offers resources to help your city tap into locally-relevant air quality information that makes it easier to understand how air quality has changed over time and what it may look like in the future.
