- The AQS Database - The Air Quality System (AQS) database contains measurements of air pollutant concentrations in the 50 United States, plus the District of Columbia, Puerto Rico, and the Virgin Islands. The measurements include both criteria air pollutants and hazardous air pollutants.
- AQS data mart - The AQS Data Mart is a database containing all of the information from the AQS system. The AQS Data Mart was built as a storehouse of air quality information that allows users to make queries of unlimited quantities of data.
- AIRData - EPA's Aerometric Information Retrieval System (AIRS) is a computer-based repository of information about airborne pollution. AIRData allows on-line access to selected data from the AIRS database.
- AIR Explorer - Air Explorer is a collection of user-friendly visualization tools for air quality analysts. The tools generate maps, graphs, and data tables dynamically. Currently, the tools access ambient concentration data from EPA's Air Quality System (AQS). This is a developmental site. We are continually designing and implementing innovative tools for analyzing and communicating air quality information.

- AIRNOW - The EPA, NOAA, NPS, tribal, state, and local agencies developed the AIRNow Web site to provide the public with easy access to national air quality information. The Web site offers daily AQI forecasts as well as real-time AQI conditions for over 300 cities across the US, and provides links to more detailed State and local air quality Web sites.
- The Center for Air Pollution Impact and Trend Analysis(CAPITA) - An excellent monitoring reference at Washington University, St. Louis. Available resources include data sets and useful software tools.
- National Association of Clean Air Agencies (NACAA) formerly STAPPA/ALAPCO - State and Territorial Air Pollution Program Administrators / Association of Local Air Pollution Control Officials homepage. Contains links to many State and Local Agency homepages and other resources.
- Tribal Air Monitoring Center - The Tribal Air Monitoring Center was created through a partnership between tribes, the Institute for Tribal Environmental Professionals, and EPA. It is the first technical training center designed specifically to meet the needs of tribes involved in air quality management and offers an array of training and support services to tribal air professionals.
- National Atmospheric Deposition Program (NADP)
NAPD is a nationwide network of precipitation monitoring sites. The network is a cooperative effort between many different groups, including the State Agricultural Experiment Stations, U.S. Geological Survey, U.S. Department of Agriculture, and numerous other governmental and private entities.
