Global oceanic angular momentum mass and motion terms
Ocean model : ECCO (based on MITgcm)
Horizontal domain : 74 degrees South to 74 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

File units : kg-m**2/s 1. The tabulated date corresponds to the midpoint of the 6-hour-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) = 1.35566307E+29 1.02386255E+29 2.93882176E+30
The mean OAM motion term (kg-m**2/s; x,y,z) = -1.05351122E+24 6.12095202E+23 9.85072987E+24
