Seasonal Air Quality Reports
Seasonal air quality reports are typically issued twice per year to provide quick updates regarding the status of air quality in Maryland during the summer months (April/May through September) for ozone and year-round (January through December) for fine particle pollution. These reports are typically prepared before data has been fully quality controlled and finalized by the Ambient Air Monitoring Program staff. These reports should be considered preliminary unless noted otherwise. Click on the appropriate link below to download the PDF document.
