All files are on native model grid and the volume files have been interpolated to fixed isolevels (Z -levels).

  1. Full 3d volume global files.

    Variables: Salinity (3zsio), Temperature (3ztio), u-velocity (3zuio), v-velocity (3zvio)

    33 isolevels with depths (in m) = 0, 10, 20, 30, 50, 75, 100, 125, 150, 200, 250, 300, 400, 500, 600, 700, 800, 900, 1000, 1100, 1200, 1300, 1400, 1500, 1750, 2000, 2500, 3000, 3500, 4000, 4500, 5000, 5500 ;

    Frequency: Daily (n024, n048, f024, f048, f072, f096, f120, f144)

    Examples:
    rtofs_glo_3dz_n024_daily_3ztio.nc
    Description: 24 hour nowcast, global volume 3D file on Z levels for temperature.
    rtofs_glo_3dz_f120_daily_3zvio.nc
