Gia Grace Apr 2026

To accurately measure current ice loss in Antarctica or Greenland, scientists must subtract the GIA signal from the total gravity signal measured by GRACE.

Twin satellite missions that measure changes in Earth's gravity field over time. These changes indicate how mass—mostly water and ice—moves around the planet. 2. Why GIA is Vital to GRACE Data gia grace

GIA-corrected GRACE data helps determine that land-to-ocean freshwater exchange has contributed roughly 1.2 mm per year to global sea level rise. To accurately measure current ice loss in Antarctica
