Reading Flow City Maps

Flow city maps show annual air pollution averages with hyper-local accuracy to help you explore your city and find fresh-air.

Data for these maps comes from the Plume Labs AI-powered environmental data platform. We use a land use regression model, taking into account air quality station readings, traffic counts and a variety of other data sources, to plot street-by-street readings to help you plan your day.

Use the filters in the top right of the screen to change the pollutants on display. Switch cities to compare your location to other major metropolitan areas.
