A review of dry deposition measurement techniques is presented, focusing on surrogate surfaces. Detailed field data from the literature are available for three types of collectors: filter paper with rainshields positioned overhead, Petri dishes, and flat Teflon or polyethylene plates. The data suggest that deposition velocities of submicron particles increase in the order flat plates LT AN BR Petri dishes LT AN BR filter paper. For supermicron particles, the order is filter paper LT AN BR Petri dishes LT AN BR flat plates. These results are interpreted in terms of the geometry of the collector, surface roughness, and peripheral shielding of the surface.
