Abstract

Abstract The dry deposition of PAN to grass, soil and water surfaces has been studied in a wind tunnel. Grass and soil were found to remove PAN with deposition velocity ( vg) around 0.25 cm s −1, but seawater and deionised water surfaces did not remove PAN at appreciable rates ( v g < 0.02 cm s −1). The diurnal variation of PAN concentration at ground level can be explained in terms of photochemical production during daylight hours and deposition continuing during the night.
