New ESMGFZ loading products for global long-term stable elastic surface deformations consistent with ECMWF ERA5 and GRACE de-aliasing AOD1B 07

GFZ provides elastic surface deformation estimates caused by atmospheric surface pressure, ocean bottom pressure, terrestrial water storage, and barystatic sea level variations on global grids. To keep those loading deformations consistent with the latest GRACE de-aliasing products AOD1B R07 we updated the loading products by using ECMWF ERA5 atmospheric forcing, the latest MPIOM ocean model, and the latest hydrological model release from LISFLOOD. We present some statistics on the new ESMGFZ loading deformation products to demonstrate its enhanced long-term stability and suitability for the realization of future high accurate terrestrial reference systems. Especially the hydrological loading component benefits now from the new LISFLOOD terrestrial water storage estimates forced with ECMWF ERA5 atmospheric data and simulated on a global high spatial resolution grid of 0.05° to resolve high deformation amplitudes in the vicinity of large rivers, lakes, and dams. The new ESMGFZ loading products cover the period 1960 to the present.
