Seasonal changes in the European gravity field from GRACE: A comparison with superconducting gravimeters and hydrology model predictions
This paper is devoted to the investigation of seasonal changes of the Earth's gravity field
from GRACE satellites and the comparison with surface gravity measurements in Europe
from the Global Geodynamics Project (GGP) sub-network, as well as with recent hydrology
models for continental soil moisture and snow. We used gravity maps in Europe retrieved
from the initial GRACE monthly solutions spanning a 21-month duration from April 2002 to
December 2003 for various truncation levels of the initial spherical harmonic decomposition …
