   ECMWF Ocean Reanalysis System 4 (ORAS4) Global1958-2009 Data available

The ORAS4 data produced in real time (from January 2010 onwards) is not recommended for integrated climate quantities and trends. Therefore we offer just the period from 1958 to 2009. Model: NEMO V3.0
Resolution: (ORCA1_Z42): Horizontal 1°x1° with equatorial refinement (0.3). 42 vertical levels, about 10m-15m level thickness in upper 200m.
Data assimilated: Temperature and Salinity profiles from the EN3 v2a XBT bias corrected database (1958-2009), including XBT, CTD, Argo, Mooring, and from realtime GTS thereafter. Along track altimeter sea level anomalies and global trends from AVISO. SST and sea-ice are from the ERA-40 archive prior to November 1981, from the NCEP OI v2 weekly product (1981 until December 2009) and , and from OSTIA analysis from January 2010 onwards.The SST and sea-ice information is used to constrain the upper level ocean temperature via a newtonian relaxation scheme.
Assimilation method: NEMOVAR in its 3D-var FGAT mode. The assimilation window is 10 days. A bias correction scheme is used to correct the model/forcing errors.
Forcing and relaxation used: Daily surface fluxes of heat, momentum and fresh water are used. Prior to 1989, the surface fluxes are from the ERA-40 atmospheric reanalysis. From the period 1989-2009, the surface fluxes are from ERA-Interim reanalysis. From 2010 onwards, when ORAS4 started operational running, daily surface fluxes were derived from the operational ECMWF atmospheric analysis.
