Welcome to Breathe Baltimore: A Community-Based Air Quality Monitoring Project in Baltimore

Breathe Baltimore is a collaborative effort and co-led by the Environmental Justice Journalism Initiative (EJJI) and the Smithsonian Environmental Research Center (SERC). The project’s goal is to create a low-cost air quality monitoring network that can provide data to support communities suffering from poor air quality in South Baltimore. 

The project’s goal is to create a low-cost air quality monitoring network that can provide data to support communities suffering from poor air quality in South Baltimore. 

We're currently in the first phase of setting up and testing 15 sensors—most are in South Baltimore with others around the city. These sensors will measure particulate pollution, ozone, and other emissions, and the data will be made available to the public. 

One sensor has been deployed, testing is underway, and the additional 14 sites are still being selected. SERC and EJJI are committed to choosing sites relevant to Baltimore communities and understanding city pollution patterns.

This project is made possible by funding from the Our Shared Future: Life on a Sustainable Planet initiative.
