Vegetation—The missing sink in the global cycle of carbonyl sulphide (COS)
Abstract It has been suggested that carbonyl sulphide (COS) represents the major form of atmospheric sulphur on a global scale, and that oxidation of COS in the stratosphere may affect the climate by influencing the formation of the sulphate aerosol layer. Despite the apparent importance of COS to the global environment, considerable uncertainties remain as to its pathways in the atmosphere, particularly in regard to its sinks. In this paper, we review evidence from studies on deposition of COS to plants which provides preliminary confirmation of the hypothesis that uptake of COS by vegetation may be the major global sink for the gas, accounting for 2–5 Tg y−1 (Tg = 1012g). In contrast, uptake by soil can account for a maximum of only 0.04 Tg y−1. Confirmation of these estimates must await measurements of COS flux to vegetation representative of the major biomes of the world.
