23 vertical levels with a resolution of 10 m thickness at the surface, increasing to 500 m thickness for depths greater than 2200 m

Surface forcing

Daily fields from NCEP/NCAR Reanalysis I for 1992-2006. Sea surface temperatures (SSTs) are relaxed (two week timescale) to 1992-2006 satellite-based estimates [19] .
