The Ambient Air Monitoring Program is responsible for measuring ground-level concentrations of criteria pollutants, air toxics, and meteorology.  Special research monitoring initiatives are also carried out to measure atmospheric parameters on more highly resolved scales of atmospheric chemistry, time, and space in order to better characterize issues surrounding air quality planning and regulations development.  The program performs quality control, quality assurance, and analysis of the measurements and is also responsible for coordination of 3D air-shed grid modeling, year-round daily air quality forecasts, and AQI reporting.  Use the links listed above to navigate through the various sections.
