The scenic beauty of Big Bend National Park is often spoiled by haze, obscuring its many vistas. In addition, Big Bend is one of the few monitored national parks in which haze has been increasing since the late 1980s. In 1999, the National Park Service (NPS) and the U.S. Environmental Protection Agency (EPA) carried out the Big Bend Regional Aerosol and Visibility Observational (BRAVO) study. Other participating agencies were the Texas Commission on Environmental Quality (TCEQ) and the Electric Power Research Institute (EPRI). The primary objectives of BRAVO were to determine the composition and optical properties of the haze and to quantify the contribution of major sulfur dioxide sources and source regions within Mexico and the United States to the haze. The BRAVO study involved a fourmonth intensive monitoring period from July through October 1999, followed by a four-year data analysis and modeling effort examining the BRAVO data and past data collected at Big Bend NP. This document is a summary of the key findings from research conducted by the National Park Service and its partners
