The RTOFS Global model is the Navy HYCOM model with wind forcing from the GFS model. 
Global HYCOM is run at NOAA/NCEP by the Marine Modeling Analysis Branch (MMAB) and became operational
on Tuesday, October 25. 

Files found here:
   grtofs_uv_YYYYMMDD.tar.gz          1.8 GB
        Contains u_velocity and v_velocity on a standard Lat/Lon grid from -78.64 deg S to 47 deg N. 
	North of 47 deg N, the grid is tri-polar curvilinear, the native model
	grid. Time steps are from 0 - 72 hours at a 3 hour interval.
 
   grtofs_sst_YYYYMMDD.tar.gz      1.6 GB
        Contains SST on a standard Lat/Lon grid from -78.64 deg S to 47 deg N.
        North of 47 deg N, the grid is tri-polar curvilinear, the native model
        grid. Time steps are from 0 - 72 hours at a 3 hour interval. 
            
   grtofs_uv_YYYYMMDD_day4.nc.gz and grtofs_uv_YYYYMMDD_day5.nc.gz 290 MB
        Days 4 and 5 U and V currents like files above for 0 - 72 hours.
  
   grtofs_sst_YYYYMMDD_day4.nc.gz and grtofs_sst_YYYYMMDD_day5.nc.gz 290 MB
        Days 4 and 5 SST like files above for 0 - 72 hours.
 
   rtofs_glo_3dz_reg1_YYYYMMDD.tar.gz (corresponds to NCOM Region 1)   1.3 GB
        Contains salinity, temperature and currents at 10 depths from the
	surface to 5000 m. The region covered is 0 to 80 deg N Lat and -40 to -100 deg W Lon.
        The region is similar to and encompasses the area covered by the NCOM global Region 1 files.
        North of 47 deg N, the grid is tri-polar curvilinear, the native model
        grid. Time steps are from 0 - 144 hours at a 6 hour interval.

   rtofs_glo_3dz_reg2_YYYYMMDD.tar.gz (corresponds to NCOM Region7)    1.6 GB
        Contains salinity, temperature and currents at 10 depths from the
        surface to 5000 m. The region covered is 10 to 75 deg N Lat and -74 to -158 deg W Lon.
        The region encompasses the area covered by the NCOM global Region 7 files and
        also extends east to cover the Gulf of Mexico.
        North of 47 deg N, the grid is tri-polar curvilinear, the native model
        grid. Time steps are from 0 - 144 hours at a 6 hour interval.
