Global Ocean Tide induced Mass-redistribution for Satellite Gravimetry
The Tidal Model forced by Ephemerides (Thomas et al., 2001; Weis et al., 2008) is a purely hydrodynamic, barotropic tidal simulation. After recent updates of bathymetric data, dissipation channels and the handling of Self-Attraction and Loading it is now possible to derive M2 tidal-dynamics (the main lunar tide), that deviate from open ocean tide-gauge measurements by 4.84 cm root-mean-square (publication in preparation). The obtained mass-redistribution patterns of ocean and solid earth are transformed into Stokes Coefficients and can be used for satellite gravimetric purposes. They are provided in resemblance to the AOD1B-format.
