Abstract Early in 1990 the National Research Council established the Committee on Haze in the National Parks and Wilderness Areas to address a number of questions related to visibility and its degradation in these pristine areas, including methods for determining anthropogenic source contributions to haze and for considering alternative source control measures. In the final report, the committee addresses the broader-scale issues of regional haze. The report discusses visibility conditions in the United States, the legal and institutional context of visibility protection programs, the scientific aspects of haze formation and visibility impairment, methods for identifying and apportioning the components of haze, and the relationship of emission controls to visibility.
