LDCmgm90 is a monthly geopotential model set complete from degree and order 2 to 90, derived from various GRACE/SLR (Satellite Laser Ranging) monthly geopotential + Various GCM (General Circulation Model) outputs + ERP (Earth Rotational Parameter) measurement constraints using the Least Difference Combination (LDC) method. Therefore, LDCmgm90 has the same functions of the GRACE monthly geopotential model sets as released by different institutes, such as Center for Space Research (CSR), Deutsches GeoForschungsZentrum (GFZ), Jet Propulsion Laboratory (JPL) and Graz University of Technology (TUG), but with a number of defects or limitations in GRACE data removed. For a full description about how LDCmgm90 overcomes the defects in common GRACE data, one can refer to this presentation given at the TibXS2019 meeting.
