Air-sea fluxes of transient atmospheric species.

The air-to-sea fluxes of the major reactive tropospheric gases and radicals have been estimated from the two-layer stagnant film model by using concentrations appropriate for the unpolluted marine troposphere and by taking into account effects of species solubility and chemical reactivity on the exchange rate. Nearly all of the transfers appear to be limited by gas-phase diffusion, in which case the exchange rate is equivalent to a conventional deposition velocity. The largest fluxes are associated with acids (HN0₃, HCl) and the more abundant molecular and radical transients in the atmosphere. -from Authors marine troposphere exchange acids
