Profiles of CF 2 Cl 2 , CFCl 3 , CCl 4 , and N 2 O in the lower stratosphere are reported from measurements made during a meridional survey in the Northern Hemisphere in the fall of 1976. The latitude distributions obtained show a marked decrease in mixing ratio with increasing latitude from about lat. 7°N in the region of the Intertropical Convergence Zone to about lat. 79°N along the 159°W meridian. The results suggest the importance of meridional transport and mixing in the stratosphere in accounting, at least in part, for the observed profile variation with latitude.
