ECMWF Ocean ReAnalysis ORA-XBTc

Area: Global

Period: 1959-2008

Data available: YES

Model: HOPE
Resolution: Horizontal 1°x1° with equatorial refinement (0.3). 29 vertical levels, about 10m-15m level thickness in upper 200 m.
Data assimilated: Temperature and Salinity profiles from the EN3 database (1959-2007), including XBT, CTD, Argo, Mooring, and from realtime GTS thereafter. Altimeter sea level anomalies maps and trends from AVISO, plus XBT corrections (Wijffels et al 2008). Operational GTS data thereafter.
Assimilation method: Multivariate OI + Bias correction
Forcing and relaxation used: ER40 (precip corrected) daily fluxes from 1959-2002. ECMWF operational NWP fluxes therefater. SST as in ERA-40 until 1982 and the weekly NOAA oiv2 1x1 from 1982 onwards.
