About
The U.S. EPA, NOAA, NPS, tribal, state, an … The U.S. EPA, NOAA, NPS, tribal, state, and local agencies developed AIRNow to provide the public, the media, and decision-makers with easy access to nationwide air quality information. The main web site offers daily [http://airnow.gov/index.cfm?action=static.aqi Air Quality Index] (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 primary purposes of AIRNow are to 1) collect and provide information to enable the public and others to take make health-based decisions, 2) provide information exchange and data access for local, tribal, state, and federal air quality agencies, and 3) provide real-time data to other research and operational data systems (NASA, NOAA, Universities, etc.).

DataSystemHistory
The roots of the AIRNow program go back to … The roots of the AIRNow program go back to 1995 when the American Lung Association of Maryland developed ozone pollution maps that regularly appeared on television weather broadcasts in the Washington, D.C. area. Although very useful and informative to the public, the effort needed to produce these maps (data transfer, quality control, processing, etc.) was substantial and too costly to continue the following year. In the United States, air pollution problems tend to be regional in nature. Because ozone measurements collected by numerous state and local agencies were not centrally available for mapping, in 1997 EPA developed a regional Ozone Mapping System to automatically transfer data to a central location, perform data conversion and quality control, and generate animated ozone maps in near real-time. This system would be the starting point of AIRNow.
AIRNow expanded rapidly with funding from one of President Clinton’s eGovernment initiatives, EMPACT (Environmental Monitoring for Public Access and Community Tracking). The goal of EMPACT was to take advantage of new technologies for providing environmental information to the public in real time, including: 1) Collecting, managing, and distributing time-relevant environmental information and 2) Providing the public with easy-to-understand information they can use in making informed, day-to-day decisions. AIRNow was the largest and most successful EMPACT project. Funds from EMPACT enabled states to purchase new hardware and software needed to upgrade their data collection infrastructure and effectively participate in AIRNow.
Today the AIRNow program continues to grow to include other pollutants and meteorological data. State and local agencies find the AIRNow program to be a critical tool for protecting public health by providing their citizens with real-time air quality information.
