The American Lung Association has released a report titled “Something in the Air: Bridging the Air Quality Data Gap with Satellite Technology.” The report utilizes satellite-derived data to suggest that St. Tammany Parish may experience unhealthy levels of particle pollution. Notably, this parish currently lacks ground-based monitors to track such pollution.
The report underscores the potential of satellite technology to enhance the existing air quality monitoring framework in the U.S. It focuses on fine particulate matter (PM2.5), known for its adverse health effects, and suggests that emerging technologies like satellites can offer crucial air quality insights, especially for communities without official monitoring systems.
Located in southeastern Louisiana, St. Tammany Parish is part of the greater New Orleans area and has seen significant population growth. Of the ten parishes and one county in this metropolitan region, five are monitored and have received satisfactory ratings for annual particle pollution according to the 2024 “State of the Air” report. However, satellite data indicates higher pollution levels in St. Tammany Parish compared to nearby areas. These findings might be influenced by factors such as warmer and wetter climates prevalent in this southeastern region, suggesting a need for further investigation.
Eric Weinzettle, director of advocacy for Louisiana at the American Lung Association, stated: “The air quality in St. Tammany Parish is influenced by local and regional industrial activities and by vehicle emissions from resident commuters and tourists using the three interstate highways that run through the parish.” He added that despite the absence of an official monitor, "the satellite-derived data used in this report shows concerning levels of particle pollution." Weinzettle expressed hope that such reports would provide more communities with vital information about air quality so they could better protect their health.
Fine particle pollution consists of minuscule solid and liquid particles from sources like wildfires, power plants, vehicles, and wood-burning stoves. These particles pose serious health risks including asthma attacks, heart attacks, strokes, lung cancer, and even death. According to recent data from 2024’s “State of the Air” report, 65 million people reside in counties experiencing unhealthy spikes in particle pollution—the highest figure recorded over 14 years.
