AB: Fast response measurements of particle size distributions, bulk submicron particle composition, and single particle composition were made aboard the NOAA WP-3D research aircraft over the eastern Pacific Ocean and the western coast of North America. Simultaneous measurements of gas-phase tracers and photochemically reactive compounds, and meteorological analyses, show evidence of long-range transport of layers of aerosol particles from anthropogenic and biomass/biofuel sources in east and southeast Asia. The aerosol layers were vertically discrete and were often correlated with CO, NO$_{y}$, O$_{3}$, organic compounds, and meteorological features. Four distinct types of particles layers were encountered: 1) associated with biomass/biofuel combustion; 2) associated with urban and/or industrial sources but no SO$_{2}$; 3) associated with urban and/or industrial sources including SO$_{2}$; and 4) containing crustal material not associated with identifiable anthropogenic or biomass burning influence.
