Rind, D., and J. Lerner, 1996: Use of on-line tracers as a diagnostic tool in general circulation model development: 1. Horizontal and vertical transport in the troposphere. J. Geophys. Res., 101, 12667-12683, doi:10.1029/96JD00551.

The use of passive on-line tracers in a general circulation model (GCM) developmental process is discussed. CFC-11 and ⁸⁵Kr are used to evaluate interhemispheric transport. It is shown that new boundary layer and convective parameterizations lead to reductions in the interhemispheric exchange times to values in close agreement with observations of little more than one year. Radon 222 is used to evaluate mixing away from the surface. The new convection scheme produces smaller convective fluxes, which substantially reduce the high-altitude concentrations of ²²²Rn equatorward of 30° latitude. While this result is in better agreement with other models, scarcity of observations prevent any conclusion as to which formulation is more accurate. The effect of altered numerical schemes for solution of the momentum and energy equations in the GCM is shown to have little influence on the model's interhemispheric transport or vertical mixing. Finer vertical resolution increases convective mixing of ²²²Rn somewhat and allows for larger pollution concentrations of CFC-11 in the boundary layer. Employing on-line passive tracers in the course of model development should allow for imporvements in a GCM-s horizontal and vertical fluxes and optimization of the model for atmospheric chemistry purposes.
