Finite Element Sea ice – Ocean Model
the Earth’s time-variable and static gravity field with an unprecedented accuracy. As fluctuations of the gravity field on sub-annual time scales are mainly induced by mass redistribution on the Earth’s surface, GRACE is potentially able to monitor oceanic mass variability and redistribution.
