Technical Air Pollution Resources
National Ambient Air Quality Standards (NAAQS)
- Scientific and technical information about NAAQS reviews
- This site provides scientific and technical information about current and prior reviews of the six common air pollutants.
Air Modeling
- Support Center for Regulatory Atmospheric Modeling (SCRAM)
- Atmospheric dispersion models that support Clean Air Act regulatory programs.
Air Monitoring
- Air Quality System (AQS)
- AQS provides data from thousands of ambient air monitors, meteorological data, and data quality assurance/quality control information.
- Ambient Monitoring Technology Information Center (AMTIC)
- AMTIC has information on ambient air quality monitoring programs, monitoring methods, quality assurance and control procedures, and federal regulations related to ambient air quality monitoring.
Air Emissions
- Air Emissions Measurement Center (EMC)
- EMC provides information on test methods for measuring air pollutants from smokestacks and other industrial sources.
- Clean Air Technology Center (CATC)
- CATC provides access to resources about air pollution prevention and control technologies, including the RACT/BACT/LAER Clearinghouse.
- Clearinghouse for Inventories and Emissions Factors (CHIEF)
- CHIEF provides information on air emissions inventories and modeling, emissions factors, electronic reporting and the emissions monitoring knowledge base.
Analyzing Air Pollution Impacts and Control
- Air Quality Analysis
- AQA provides the documented analyses that support the NAAQS Review process, as well as other documented analyses of special interest.
- Economic and Cost Analysis (ECAS) for Air Pollution Regulations
- ECAS provides tools, including databases and models, for analyzing costs, benefits, and economic impacts of air quality management strategies, programs, and regulations.
- Fate, Exposure, and Risk Analysis (FERA)
- FERA provides tools used to evaluate the health risks and environmental effects associated with exposure to criteria air pollutants and toxic air pollutants.
