A one-dimensional isothermal transport model is developed for the prevailing minor gases in the upper atmosphere of Titan. Solving the equation governing vertical transport in the presence of both molecular and eddy diffusion for CH4 and (C2H6 + C2H4 + C2H2) with a common height-dependent eddy diffusion coefficient for a spherical geometry, and utilizing nominal values for the derived abundances of methane and the C2-hydrocarbons as boundary conditions, the homopause is found at an altitude of 660 km. The eddy-diffusion coefficient has a value of approximately 1 x 10 to the 6th sq cm/sec at the homopause. The column-integrated destruction rate of CH4 is balanced by a methane flux of 5.3 x 10 to the 9th/sq cm sec referenced to the planetary surface.
