This study, which was part of a multi-university AEOLOS investigation, involved an assessment of the spatial and temporal variations in the dry deposition fluxes and mass size distributions (MSDs) of total mass, crustal (aluminum and magnesium), and anthropogenic (lead and copper) metals over the southern basin of Lake Michigan. In general the average measured fluxes in Chicago were higher and more variable than fluxes measured away from Chicago. A multi-step modeling procedure that used measured atmospheric mass size distributions and modeled deposition velocities was used to calculate the dry deposition flux for comparison to the measured flux data. In general calculated fluxes were in good agreement with measured fluxes. Modeling results indicate that the majority of the flux (>98 %) was due to particles >6.5 {mu}m in size. 3 refs., 5 figs., 1 tab.
