Characteristics of Perturbations in Recent Length of Day and Polar Motion

Characteristics of Perturbations in Recent Length of Day and Polar Motion

Various features of the existing perturbations in the Earth’s spin rotation are investigated for the recent and most reliable data by spectral analysis, filtering, and comparison with idealized model. First, theory of Earth’s spin rotational perturbation is briefly re-derived in the Earth-fixed coor...
