| Content | oceanic center-of-mass (COM), and total ocean mass (includes effects of sea ice) Ocean model : ECCO Version 4 Release 3(based on MITgcm) Horizontal domain : Global Horizontal resolution : Variable spacing ranging from 22 km to 111 km (see Forget et al. 2015, section 2) Vertical resolution : 50 levels ranging in thickness from 10 m at surface to 460 m at depth Boussinesq model? : Yes Tabulated COM corrected for volume changes due to steric effects? : Yes Does not include mass effects from net real freshwater flux Ocean model forcing : 6-hourly ERA-Interim values adjusted by optimization (see Forget et al. 2015, section 3.5); no pressure forcing used Data assimilated : sea level altimetry, in situ temperature/salinity, satellite SST/SSS, bottom pressure, sea-ice concentration (see Fukumori et al. 2018) |
| Documentation | File units : meters for COM, kg for mass The mean has been removed from the tabulated COM and mass values. The mean COM (meters; x,y,z) = -7.63698852E+05 -4.66370919E+05 -8.75361400E+05 The mean total ocean mass (kg) = 1.37371282E+21 This ocean mass can be used to convert the COM values given here to geocenter values. |
