ESS Open Archive | The study shows that smoke from the record 2023 Canadian wildfires significantly degraded Lake Michigan–region air quality, driving most PM₂.₅ exceedances and influencing one of two summer ozone events, while model–observation comparisons suggest the smoke’s ozone-dampening aerosol effects were likely stronger than simulations indicated.

Arizona PBS | The Clean Air Act has significantly reduced major air pollutants and improved public health, though further progress may be challenging, as discussed by experts Dr. Tracey Holloway and Emily Schilling.

PAHO | PAHO/WHO conducted air-quality assessments and on-the-job training in Turks and Caicos to help local authorities build lasting capacity for managing indoor environmental quality in public facilities.

United Nations Development Programme | Air pollution remains a major public health challenge in Viet Nam, and a 2025 pilot led by UNDP and AirGradient tested low-cost, community-operated sensors to expand hyperlocal monitoring, build local capacity, and generate data to support targeted pollution reduction efforts.
