Annual Data Summary 2007 Gaseous Pollutant Monitoring Program Ozone, Sulfur Dioxide, Particulate Matter, Meteorological Observations. Natural Resource Report

摘要

The National Park Service Air Resources Division (NPS ARD) is responsible for providing policy and technical support to national parks on air quality issues. NPS ARD has established monitoring networks for gaseous pollutants, wet and dry deposition, and visibility. This 2007 annual data summary report summarizes data from the ozone monitoring network. Dry deposition data are summarized by the Clean Air Status and Trends Network (CASTNet); wet deposition by the National Atmospheric Deposition Program (NADP); and visibility by the Interagency Monitoring of Visual Environments (IMPROVE) program. The NPS monitoring objectives call for the collection of data to support the National Park Services involvement in both the development of state air quality control plans, and the evaluation of permit applications for new or expanding air pollution sources wishing to locate near park units. The Clean Air Act gives federal land managers an affirmative responsibility to protect air quality related values in Class I areas and to assess whether new sources will have an adverse impact on park resources and values. Information on air quality in NPS units can also be used to evaluate the performance of atmospheric models that simulate transport and impacts of pollutants.
