Platform Pittsburgh: Deploying Real-Time Multi-Pollutant Sensors (RAMP)

Since 2016, this project has deployed and operated 50 low-cost RAMP air pollutant sensors in Pittsburgh and surrounding Allegheny County. The RAMPs measure gas-phase (CO, CO2, O3, NO, NO2 and SO2) and particulate pollutants (PM2.5). Our dense sensor network provides real-time, neighborhood-level air pollutant data, and to the best of our knowledge is the largest network of low-cost air pollutant sensors in the U.S.

We can use RAMP data for numerous uses: to quantify people's exposure to air pollution, to help regional planners develop traffic control strategies that minimize pollutant levels or people's exposures, to measure emissions from the traffic fleet, and to track progress with CO2 reduction goals associated with traffic sources in Pittsburgh. We also work with the community to provide local air quality data freely as a tool for community groups to further outreach efforts.
