A deep stratospheric depletion of CO is found in Titan's atmosphere comparing millimetric and infrared observations (Marten et al., 1988; Lutz et al., 1983). It is suggested that absorption of CO on aerosols in the region of Titan's atmosphere where methane is expected to condense may change the vertical distribution of CO below about 40 km. Aerosols slowly pervading through the methane condensation region cloud transport enough CO to generate the observed tropospheric enrichment provided the sticking coefficient epsilon (fraction of collisions yielding absorption) is 0.0006, assuming the same eddy diffusion coefficient K as in the earth troposphere. In the case of a lower mixing rate, generally favored, smaller values of epsilon are allowed (down to about 10 to the -6th). Besides, the final radius of methand particles, just above the region where methane evaporates (below about 10 km), must be 100 microns within a factor of 10. The hypothesis presented in this paper, if it is confirmed by laboratory measurements, could be an indirect evidence for large amounts of CH4 ice in the Titanian atmosphere.
