The American Lung Association has published a report titled "Something in the Air: Bridging the Air Quality Data Gap with Satellite Technology," which utilizes satellite data to suggest that Mohave County, Arizona, may experience unhealthy levels of particle pollution. The county currently lacks ground-based monitors for tracking such pollution.
The report emphasizes the potential role of satellite technology in enhancing the U.S. air quality monitoring network, particularly for fine particulate matter (PM2.5), known to be harmful to human health. JoAnna Strother, director of advocacy for the American Lung Association in Arizona, commented on Mohave County's unexpected ranking among the top ten unmonitored counties in terms of annual particle pollution levels. She attributed this partly to its proximity to San Bernardino County, California, and Clark County, Nevada—both identified as having poor air quality.
"While Mohave County doesn’t have an official air quality monitor, the satellite-derived data used in this report shows concerning levels of particle pollution," said Strother. "Our hope is that this report results in more communities having valuable information about air quality levels so they can better protect their health."
Key findings from the report indicate that around 300 out of 2,700 U.S. counties without complete monitoring data might have high enough PM2.5 levels to receive failing grades according to previous reports. Besides Mohave County, other counties like Collin in Texas and Forsyth in Georgia were also highlighted for potentially concerning pollution levels based on satellite data.
The report underscores that while satellite-derived data is not meant to replace regulatory monitors' accuracy and compliance assurance, it can complement them by offering broader insights into air quality management.
This new focus on fine particle pollution highlights its sources and risks—ranging from wildfires and vehicle emissions to power plants—and its serious health impacts like asthma attacks and lung cancer.
"Something in the Air: Bridging the Air Quality Data Gap with Satellite Technology" urges actions from various stakeholders including EPA and states to fully implement updated standards for PM2.5 and explore integrating satellite technology into existing systems.
Individuals are encouraged to use resources like EPA’s AirNow website for current air quality conditions and participate in advocacy through networks such as the American Lung Association’s Lung Action Network.
