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 CEDA and can be accessed anonymously via:
sparc-ftp.ceda.ac.uk/sparc/ref_clim/randel/trace_gases/ozone
Please use an ftp client such as FileZilla to connect to the ftp server as many browsers, including chrome, no longer support urls using the ftp protocol. Please refer to the README file for more information.
