Global RTOFS Product Description


The Global RTOFS model data is in NetCDF format, and will be distributed on both the Operational FTP server (FTPPRD), and the NOMADS data server.

NetCDF Product description

NetCDF file names are:
Hourly Surface files: rtofs_glo_2ds_[n,f]XXX_CCCC.nc
6-Hourly and Daily Volume files: rtofs_glo_3dz_[n,f]XXX_DDDD_EEEE.nc
where:
n=nowcast
f=forecast
XXX=hours (024 for nowcast and 000-192 for forecast)
CCCC=[diag, prog, ice]
DDDD=[daily, 6hrly_hvr]
if 6hrly_hvr then EEEE=[US_east,US_west,alaska]
if daily then EEEE= 3z[s,t,u,v]io

Surface Fields (2ds)

diag stands for diagnostic variables:
ssh
surface_boundary_layer_thickness
mixed_layer_thickness
prog stands for prognostic variables:
u_velocity
v_velocity
sst
sss
layer_density
ice sea ice variables (from CICE, coupled to RTOFS):
ice_coverage
ice_temperature
ice_thickness
ice_uvelocity
icd_vvelocity

Volumetric Fields (3dz) defined on Z-levels:

Parameters
s= salinity
t= temperature
u= u-component
v= v-component
