BETTER UNDERSTANDING OF CLIMATE-DRIVEN ICE MASS CHANGES AND THEIR IMPACT ON SOLID EARTH IS OF EXTREME INTEREST SINCE IT HELPS UNRAVEL THE PUZZLE OF WHY AND HOW THE MELTING MIGHT EVOLVE IN THE FUTURE. THIS IS PARTICULARLY TRUE OVER GREENLAND WHERE THE ICE SHEET (GRIS) HOLDS THE EQUIVALENT OF MORE THAN 7M OF SEA LEVEL RISE AND IS EXTREMELY SENSITIVE TO CLIMATE CHANGE. HOWEVER THE DISAGREEMENT AMONG THE ESTIMATED PRESENT-DAY GRIS MASS CHANGES ARE SIGNIFICANT ESPECIALLY AT REGIONAL SCALE WHERE GIA EFFECT MAY REPRESENT A SIGNIFICANT PORTION OF THE GEODETIC MEASUREMENTS (E.G. GRACE). THUS SELF-CONSISTENT ESTIMATION OF GIA AND PRESENT-DAY GRIS MASS CHANGE IS CRUCIAL TO IMPROVE THE UNDERSTANDING OF THE SPATIAL AND TEMPORAL COMPLEXITIES OF THE COUPLED PROCESSES.
