From its website:
"AirBeat is a pilot project sponsored by the U.S. Environmental Protection Agency (EPA) specifically for the community of Roxbury. If AirBeat proves successful in Roxbury, it could become a recipe for addressing air pollution issues in many urban areas across the country.
AirBeat is one of many pilot projects funded by the EPA under a program called Environmental Monitoring for Public Access and Community Tracking (EMPACT). The purpose of EMPACT is to make timely environmental information available to communities in a format that is useable and easy to understand. In the past, this information was usually technical and took weeks or months to become publicly available. However, with the advent of new technologies and the Internet, environmental data can be made available to the public within minutes or hours. This allows people to make informed, day-to-day decisions about their lives that can protect their health and the environment."
