Time variable gravity field recovery in local areas by means of Slepian functions

• Combining multiple satellites yields consistent results with a small residual effect which might be an indication for suboptimal weighting

Comparison and combination of CHAMP and GRACE data for gravity field analysisM.

In conclusion, a framework has been created in or- der to derive a refined model for the gravity field in local areas using the LOS gradiometry in combi- nation with position

In this paper, we compare time series of terrestrial gravity (including the contribution due to surface displacement) as measured by superconducting gravimeters

Estimates of individual mass variations are provided via the di fferent geophysical models for each component of the Earth mass system, namely the atmosphere, the continental

Basic problem: no concurrent spatial and spectral limitation Objective: base function suitable for local modelling in area R... Spatial and spectral

11 Span of the difference degree RMS with respect to GGM02 S of the monthly static solutions for GRACE (dark gray) and CHAMP (light gray): the worst monthly solution of each data

• The primary observables of the GRACE system (range & range rate) are connected to gravity field quantities through variational equations (numerical integration) or
