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. Get involved and know what we are breathing each month by downloading the quality of air monthly reports!
