Air Quality Monitoring History Database
Reports from this site provide information about when, where, and what the National Park Service (NPS) monitors. This database is not a comprehensive list of all air quality monitors in the United States.
Since the late 1970's, the NPS has monitored visibility, gaseous pollutants (mainly ozone), and atmospheric deposition. Meteorological monitoring is also conducted at many locations to aid in interpretation of measured air pollutant levels. Monitoring networks that the NPS participates in include:
- Interagency Monitoring of Protected Visual Environments (IMPROVE)
- National Atmospheric Deposition Program/National Trends Network (NADP/NTN)
- Clean Air Status and Trends Network (CASTNet)
- Gaseous Pollutant and Meteorology Program (GPMP)
