Analysis of 5½ years of Lageos satellite range data reveal significant residual nodal signatures: an acceleration and annual and semiannual periods. These signatures primarily reflect variations in the zonal gravitational harmonic J2 coefficient and hence the polar moment of inertia. The implied decrease of \[Jdot]2=−3×10−11 yr−1 is consistent with both historical observations of the nontidal acceleration of the Earth's rotation and models of viscous rebound of the solid Earth from the decrease… CONTINUE READING
