| Content | Global oceanic angular momentum mass and motion terms Ocean model : ECCO (based on MITgcm) Horizontal domain : 80 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 mass term corrected for volume changes due to steric effects? : Yes 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 : Altimetric measurements of sea surface height and XBT data |
| Documentation | File units : kg-m**2/s 1. The tabulated date corresponds to the midpoint of the 1-day-long averaging interval. 2. The mean has been removed from the tabulated OAM values. The mean OAM mass term (kg-m**2/s; x,y,z) = 1.35566348E+29 1.02386224E+29 2.93882188E+30 The mean OAM motion term (kg-m**2/s; x,y,z) = -1.05385115E+24 6.45184748E+23 9.66278610E+24 |
