To accurately measure current ice loss in Antarctica or Greenland, scientists must subtract the GIA signal from the total gravity signal measured by GRACE.
Researchers use various GIA models (often grouped into "fingerprints") to adjust GRACE data, but significant uncertainties remain. gia grace
In Antarctica, GIA can account for up to 50% of the total mass change signal, making precise GIA models critical for accurate climate assessment. 3. Key Research Areas & Applications To accurately measure current ice loss in Antarctica
Models rely on assumptions about the Earth's internal viscosity. Changes in these parameters can significantly alter model fit and predictions for regions like Alaska. but significant uncertainties remain. In Antarctica
