We apply a novel technique for extracting the 2-D mass streamfunction from 3-D winds computed by a general circulation model
(GCM). The advantages of the GCM-derived advection over that derived from diabatic heating rates are twofold. First, it
unifies the tropospheric transport (the Hadley circulation) and the stratospheric transport (the Brewer-Dobson circulation).
Second, it has the realism of a full GCM. For the Earth's atmosphere, we use winds from the National Center for Climate
Prediction (NCEP). The Jupiter winds are taken from simulations obtained by the Comparative Planetology Laboratory at the
University of Louisville. The chemical tracers used were N2O and C2H6 for the terrestrial and Jovian atmospheres,
respectively.
