Climatologies of stratospheric trace gases derived from the Upper Atmosphere Research Satellite (UARS) observations are available on CEDA and can be accessed anonymously via:
sparc-ftp.ceda.ac.uk/sparc/ref_clim/randel/trace_gases/uars
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. Refer to the README file for more information including sample code.
