Exchange of Chemical Species between the Atmospheric Boundary Layer and the Reservoir Layer: An Analytical Interpretation

Abstract:The exchange of chemical species between the atmospheric boundary layer and the reservoir layer is investigated by means of an analytical solution of the conservation equation of a decaying chemical species. The exchange mechanism is governed by two parameters: the Damköhler number (the ratio of the turbulence time scale to the chemical time scale) and the ratio of a concentration scale in the atmospheric boundary layer to the concentration in the reservoir layer. Depending on the value of these two parameters, the exchange flux between the two layers can vary in sign and by several orders of magnitude. The study demonstrates to what extent chemical transformation determines the transfer of chemical species between the atmospheric boundary layer and the reservoir layer.
