The American Lung Association has released a report titled “Something in the Air: Bridging the Air Quality Data Gap with Satellite Technology.” The report uses satellite-derived data to indicate that Collin County, Texas, may experience unhealthy levels of particle pollution. Currently, there are no ground-based monitors in Collin County to track such pollution.
The report underscores the potential for satellite technology to supplement existing air quality monitoring networks across the United States. It focuses on fine particulate matter (PM2.5), which is considered one of the most harmful pollutants for human health. Emerging technologies like satellites could provide essential air quality information to communities lacking official monitoring data.
Collin County is highlighted as a significant area of concern due to its large population and proximity to urban centers such as Dallas and Fort Worth. According to Charlie Gagen, director of advocacy for the American Lung Association in Texas, "As one of the fastest-growing counties in the nation, Collin is significantly impacted by its geographic proximity to major urban hubs...While Colin County doesn’t have an official air quality monitor, the satellite-derived data used in this report shows concerning levels of particle pollution."
The report's findings suggest that up to 300 U.S. counties without complete monitoring data for PM2.5 from 2020 through 2022 might have pollution levels high enough for failing grades according to their standards. Besides Collin County, other areas highlighted include Forsyth, Georgia; Marion, Oregon; Mohave, Arizona; St. Charles, Missouri; and St. Tammany Parish, Louisiana.
Key points emphasize that while satellite data should not replace regulatory monitors' highly accurate measurements needed for compliance with air quality standards, it can complement them by identifying unmonitored areas with potentially high pollution levels.
Fine particle pollution consists of tiny particles originating from sources like wildfires and vehicle emissions and poses severe health risks including asthma attacks and heart issues. The report calls for actions from various entities:
- The EPA should fully implement updated PM2.5 standards.
- Stronger science-based standards are needed for all major pollutants.
- States should use satellite technology when creating State Implementation Plans.
- Individuals are encouraged to use resources like AirNow.gov and advocate through organizations such as the American Lung Association’s Lung Action Network.
