Wildfire Smoke Increases Ozone Pollution Across the U.S., NASA Study Finds
A NASA-funded study has revealed that wildfire smoke significantly contributes to ground-level ozone pollution across the United States, creating unhealthy air conditions far from the source of the fires. Researchers found that from 2022 to 2024, wildfires exposed an additional 43 million people in the U.S. to ozone levels exceeding federal air quality standards. The study highlights the role of wildfires in reversing years of progress in ozone control, particularly in the Midwest and West. Using advanced satellite observations, such as NASA's TEMPO mission launched in 2023, scientists can now track ozone pollution with unprecedented precision. These tools, combined with ground-based monitoring and atmospheric models, provide a clearer picture of how wildfire smoke impacts air quality across regions. The findings underscore the importance of integrating satellite data into air quality management, especially as wildfires become more frequent and intense.
