A new report released by the American Lung Association discusses the potential of satellite technology to bridge the gap in air quality monitoring in communities without ground-based monitors. The report focuses on the importance of tracking fine particulate matter (PM2.5), a harmful air pollutant, in areas lacking official monitoring data. It highlights how satellite-derived data can provide valuable insights into air quality in underserved regions.
The report reveals that many areas in the U.S. lack comprehensive air quality monitoring coverage, particularly rural regions. Satellite technology can complement existing monitoring networks by offering data in unmonitored areas. Preliminary estimates suggest that up to 300 counties with incomplete or no monitoring data for PM2.5 may have high pollution levels.
This technology has the potential to uncover more communities with poor air quality, providing a broader approach to monitoring pollution patterns and trends. While satellite data does not replace ground-based monitors, it can enhance understanding and protection of public health. The report emphasizes the importance of implementing stronger air quality standards and utilizing satellite data to improve air quality monitoring.
The American Lung Association calls for action from the EPA, states, and individuals to improve air quality, particularly in environmental justice communities. By leveraging satellite technology and supporting policies to reduce pollution, communities can better protect their health. The full report, “Something in the Air: Bridging the Air Quality Data Gap with Satellite Technology,” is available on Lung.org.
