| Content | oceanic center-of-mass (COM) Ocean model : ECCO (based on MITgcm) Horizontal domain : 78 degrees South to 80 degrees North latitude Horizontal resolution : 1/3 degree at equator to 1 degree at high latitudes by 1 degree longitude Vertical resolution : 46 levels ranging in thickness from 10 m at surface to 400 m at depth Boussinesq model? : Yes Tabulated COM corrected for volume changes due to steric effects? : No (correction is negligibly small, being 6 orders of magnitude smaller than the COM variations) Ocean model forcing : Surface wind stress : 12-hour NCEP/NCAR reanalysis Surface heat flux : Daily NCEP/NCAR reanalysis Surface freshwater flux : Daily NCEP/NCAR reanalysis (freshening only) Surface pressure : None Data assimilated : None |
| Documentation | File units : meters 1. The tabulated date corresponds to the midpoint of the 10-day-long averaging interval. 2. The tabulated values are not equi-spaced in time since the output epoch is re-set at the beginning of each calendar year. 3. The mean has been removed from the tabulated COM values. The mean oceanic COM (m; x,y,z) = -7.60792501E+05 -4.72390639E+05 -9.45089888E+05 4. The mass of the ocean model is 1.3682615632074425E+21 kg. This ocean mass can be used to convert the COM values given here to geocenter values. |
