NPS GASEOUS POLLUTANT & METEOROLOGICAL DATA ACCESS
The National Park Service Air Resources Division Gaseous Pollutant Monitoring Program (GPMP) was implemented in 1980 as part of a comprehensive effort to protect the air and other resources influenced by air quality in the Class I areas. Data from this program are used to:
- Establish existing or baseline concentrations in NPS units.
- Assess air quality trends in NPS units.
- Evaluate compliance with national air quality standards.
- Assist in the development of national and regional air pollution control policies affecting park resources.
- Provide data for atmospheric model development and evaluation.
- Identify those air pollutants with the potential to injure or damage park natural resources, monitor these pollutants, and correlate the measurable effects to existing ambient pollutant levels.
The purpose of this website, as administered by Air Resource Specialists, Inc., is to provide gaseous air pollutant and meteorological data from the
GPMP Database. The number of parameters and duration of monitoring at sites throughout the network vary over time.
Consult the
The Monitoring History Database before making your data request.
Please acknowledge the National Park Service as the source of the data if it is used in any presentations or publications.
