| Zusammenfassung |
| A parameterization for the deposition velocity of an ocean-reactive
atmospheric gas (such as ozone) is developed. The parameterization is based
on integration of the turbulent-molecular transport equation (with a
chemical source term) in the ocean. It extends previous work that only
considered reactions within the oceanic molecular sublayer. The sensitivity
of the ocean-side transport to reaction rate and wind forcing is examined. A
more complicated case with a much more reactive thin surfactant layer is
also considered. The full atmosphere-ocean deposition velocity is obtained
by matching boundary conditions at the interface. For an assumed ocean
reaction rate of 103 s−1, the enhancement for ozone deposition by
oceanic turbulence is found to be up to a factor of three for meteorological
data obtained in a recent cruise off the East Coast of the U.S. |
