Alternatively one may use the NCEP/NCAR reanalyses.
You can also view inventories of the data that DSS provided to ECMWF for their reanalysis.
An email mailing list exists to distribute bulletins from NCAR/DSS and ECMWF about ECMWF datasets at NCAR such as announcements of data updates, problems which have been discovered, and changes to software. This mailing list covers the ECMWF/TOGA (WCRP) archive as well as the reanalyses. Previous bulletins are available. If you wish to be added to this mailing list, send email to Joey Comeaux (joey@ucar.edu).
