Advances in the Unified Theory of the Rotation of the Nonrigid Earth
Abstract
Investigations of nonrigid-Earth rotation usually rely on the convolution of a transfer function with a rigid-Earth solution. A possible alternative is to develop a unified theory to encompass in only one body both rigid and nonrigid effects. It is represented in the Hamiltonian theory by Getino and Ferrandiz (GF). This theory combines the convenience of being a really analytical theory with good practical performance, since the residuals with respect to observations are also at the same plus or minus mass level as the present IERS series. We report on more recent results we obtained in the last year, not collected in the "Considerations" paper of the WGN (joint IAU/IUGG Working Group on Nutations).
