Numerical model : MPIOM (Max-Planck-Institute Ocean Model)
Horizontal domain : global
Horizontal resolution : 1.0 x 1.0 degree
Model forcing : 3h ECMWF operational data
Correction : Oceanic pressure tides are subtracted, global mass (Greatbatch) correction applied
Data assimilated : None
Notes : These AAMs are part of a set of consistently processed Earth rotation excitation
function (AAM, OAM, HAM). The ocean model MPIOM and the hydrological model LSDM were
forced consistently with operational analysis data from the ECMWF.

Data Description:
Data are values of effective angular momentum functions (EAM) of the atmosphere, the ocean, and land hydrology as calculated from 6-hourly ECMWF (European Centre for Medium-range Weather Forecasts) operational atmospheric forcing data by means of theMax Planck Institute Ocean Model (MPIOM) and the Land Surface Discharge Model(LSDM). All the data is processed consistently to the GRACE de-aliasing products AOD1BRelease 06. Model description and citation info is given in the references at the end of this file.
