Measurements of surface resistance during dry deposition of SO2 to wet and dry coniferous forest.

Abstract

Direct measurements of dry deposition of SO2 to pine trees in central Sweden have given a dry deposition velocity of 0.4 cm/s in summer and 0.1 or less in winter. Dry deposition of S in gas and particles is smaller than wet deposition. This is characteristic for a northern country at some distance from major anthropogenic SO2 emission areas. -from CEGB Digest
