Detector for dry deposition of atmospheric contaminants |
摘要 |
A detector for dry deposition of atmospheric contaminants comprised of a surrogate surface upon which the contaminants are deposited from the atmosphere; an airfoil-type surface circumferentially surrounding the surrogate surface and providing a laminar or transition boundary layer flow over the surrogate surface; and a post supporting the surrogate surface and airfoil-type surface in the atmosphere. With the detector, the flux of a contaminant in the atmosphere can then be determined from the area of the surrogate surface and the mass of contaminants collected therefrom over a given time.
