Description of Global RTOFS NetCDF files on NOMADS

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
    Description: 120 hour forecast, global volume 3D file on Z levels for v-velocity component.
  2. Surface global files.

    Variables:

    SST, SSS, U-Velocity, V-Velocity, Speed, layer Density (prognostic)

    SSH, MLD, BLD, Ice coverage, Ice thickness (diagnostic)

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

    Examples:
    rtofs_glo_2ds_n024_daily_prog.nc
    Description: 24 hour nowcast, global surface file for prognostic variables
    rtofs_glo_2ds_f072_daily_diag.nc
    Description: 72 hour forecast, global surface file for diagnostic variables
  3. Surface global files.

    Variables: SST, SSS, U-Velocity, V-Velocity, Speed, layer Density (prognostic)

    SSH, MLD, BLD, Ice coverage, Ice thickness (diagnostic)

    Frequency: 3 hours

    Examples:
    rtofs_glo_2ds_f009_3hrly_prog.nc
    Description: 9 hour forecast, global surface file for prognostic variables
    rtofs_glo_2ds_n042_3hrly_diag.nc
    Description: 42 hour nowcast, global surface file for diagnostic variables
  4. Regional volume files.

    Three regions: reg1 ( US East Coast), reg2 ( US West Coast) , reg3 ( Alaska)

  • Variables: Salinity, Temperature, u-velocity, v-velocity

    10 isolevels with depths (in m) = 0, 100, 200, 400, 700, 1000, 2000, 3000, 4000, 5000

    Frequency: Every 6 hours

    Examples:
