ERA-Interim is ECMWF's previous atmospheric reanalysis, based on a 2006 version of the IFS.  ERA-Interim data are available for dates from 1979 until 31st August 2019 but are no longer updated.  ERA5 replaced ERA-Interim in 2019.

The main differences advantages of ERA5 from against ERA-interim are

    • higher spacial resolution (137 levels, 31km; 62km for EDA).
    • higher output frequency of analysis fields (hourly, 3-hourly for EDA).
    • introduction of uncertainty estimates.
    • additional input observation types.
    • many more output parameters.
    • use of a much longer period of historical data (back to 1950).
