Ambient Air Monitoring Program

The Ambient Air Monitoring Program measures ground-level concentrations of criteria pollutants and air toxics, along with surface and aloft meteorological parameters. The Program also performs quality control, quality assurance, and analysis of the pollutant concentrations that are measured at each of the air monitoring stations located throughout Maryland. It is responsible for Air Quality Index (AQI) reporting and issuing daily air quality forecasts as well as coordination of 3D air-shed photochemical grid and dispersion modeling.

In addition, the Program collaborates with local universities to conduct special atmospheric monitoring research to better characterize aloft and surface atmospheric pollutant concentrations. These research initiatives support air quality planning and regulations development.

Air Quality Forecast Discussion:

Strong winds associated with a large storm system affecting the east coast will keep Good air quality across the region through the weekend. On Monday, high pressure begins to influence the area, causing winds to subside. Fine particle levels will increase but remain in the Good range. Under strongly inverted conditions Tuesday and Wednesday, Moderate AQI is expected for most areas. - MDE
