Global zonally averaged ozone trends as a function of height have been derived from several different sources for 1979-1996 (Randel and Wu., 1999). Trends were calculated with respect to a ozone climatology (Fortuin and Kelder, 1998). Data are available on the ftp server at /sparc/ref_clim/randel/trace_gases/ozone. Refer to the README file for more information.
