Abstract
The 1977 Clean Air Act Amendment provides for protection of visual air quality of certain federally managed lands. In support of these provisions the U.S. Environmental Protection Agency, in cooperation with the National Park Service, has sponsored a number of visibility research programs. One program involves development and operation of a western regional visibility monitoring network. The objectives of this network are to develop visibility monitoring methods, to characterize visibility in this region, and to provide data that can be used to identify sources of visibility impairment. This report describes the western network and methods used to collect and process data, the results for the period of record and quality assurance procedures. A visibility theory section is provided to define terms and concepts. Seasonal and monthly mean standard visual range values with 90 percent confidence intervals and cumulative frequency plots for each monitoring location are reported. This report covers the data collection period from summer of 1978 through fall of 1981.
