Recent advances in the spatial and temporal retrieval of land-based cryospheric change information south of 42.5° allow fairly robust construction of forward model predictions of the time-rate of change in gravity. A map-view prediction is presented for the time-rate of change in geoid,
that might be retrieved from the currently orbiting gravity space craft, CHAMP (Challenging Mini-Satellite Payload for Geophysical Research and Application) and/or GRACE (Gravity Recovery and Climate Experiment). Complementary computation of the surface gravity change,
, is also presented. The latter can be recovered from terrestrial absolute gravity measurements. Also, the computed rate of change Stokes coefficients for degree and order
1–12 may be used as reliable estimates of the Southern Hemisphere cryospheric change contribution to the global low-degree harmonic variability recorded in multidecadal satellite laser ranging (SLR) data sets.
