The AirData website gives you access to air quality data collected at outdoor monitors across the United States, Puerto Rico, and the U. S. Virgin Islands. The data comes primarily from the AQS (Air Quality System) database. You can choose from several ways of looking at the data:
- download data into a file (or view it on the screen) ... - output the data into one of AirData’s standard reports
- create graphical displays using one of the visualization tools
- investigate monitor locations using an interactive map
AirData assists a wide range of people, from the concerned citizen who wants to know how many unhealthy air quality days there were in his county last year to air quality analysts in the regulatory, academic, and health research communities who need raw data.
