OSTI ID:82339
Early in 1990, the National Research Council established the Committee on Haze in National Parks and Wilderness Areas to address visibility and its degradation in these pristine areas, including methods for determining anthropogenic source contributions to haze and for considering alternative source control measures. An interim report was completed in late 1990 on haze in the Grand Canyon and the Winter Haze Intensive Tracer Experiment. In this final report, the committee addresses the broader-scale issues of regional haze. This report discusses visibility conditions in the U.S., 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 relation of emission controls to visibility. A final chapter of conclusions and recommendations is offered.
