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).
- 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 ;
