Quality of Air Monthly Reports
In an effort to keep Maryland citizens informed about the region's air quality, the Ambient Air Monitoring Program publishes monthly air quality reports for the following forecast regions: Baltimore, Eastern Shore, Washington DC, and Western Maryland. These reports provide basic statistics regarding the two major pollutants in Maryland: ground-level ozone and fine particles, which are reported using the color-coded Air Quality Index (AQI) to relate pollutant levels to associated health effects. The reports also provide a synopsis of the weather and climate and their effects on the quality of the air we breathe. Get involved and know what we are breathing each month by downloading the quality of air monthly reports!

Disclaimer
Quality of air monthly reports are published using real-time air quality data that have not been finalized (not fully quality controlled by the Ambient Air Monitoring Program staff) and are preliminary. They are intended for informational purposes only and should not be used for regulatory purposes. In addition, reports after December 2007 reflect: (a) the revision of particulate matter standard strengthening the 24-hour level from 65 µg/m3 to 35 µg/m3 which became effective on December 18, 2006 (http://www.epa.gov/air/particlepollution/actions.html); (b) the revision of the 8-hour ozone standard from 85 ppb to 75 ppb and the revision of its Air Quality Index which became effective on May 27, 2008 (http://www.epa.gov/air/ozonepollution/actions.html); and (c) cutpoints in the proposed revision of particulate matter's Air Quality Index on January 15, 2009 (http://www.epa.gov/air/particlepollution/actions.html).
