Accounting for GIA signal in GRACE products

SUMMARY The Gravity Recovery and Climate Experiment (GRACE) observes gravitational potential anomalies that include the effects of present-day surface mass change (PDSMC)- glacial isostatic adjustment (GIA)-driven solid Earth redistribution. Therefore, GIA estimates from a forward model are commonly removed GRACE to estimate PDSMC. There several models facilitate users in using their choice, both products made available terms global gridded fields representing anomaly. GRACE-observed represented equivalent water height (EWH) with relation accounts for an elastic deformation due However, obtaining EWH fields, two relations being used: one is similar used other does not effect. This leaves possibility different values PDSMC given field. In this paper, we discuss impact problem on regional highlight need consistent treatment signals observations.
