This report addresses a study of the effects of cross-border transport on suspended particles in the Imperial Valley of California and the city of Mexicali, Baja California, Mexico . The goal of the Imperial/Mexicali PM10 Study was to determine the causes of standard exceedances on the U.S. side of the border and to determine the effects of cross-border transport on these exceedances. The major management goal was to develop and transfer advanced sampling, analysis, and modeling technologies to the U.S. and Mexico air pollution control organizations. This technology can then be applied to quantify the effects of emissions reductions strategies on ambient concentrations in both the United States and Mexico.
