Abstract
The model values of the mantle quality factor Q=40±20 and the Chandler wobble period T=435–436 days are obtained by numerical modeling of the yearly and Chandler components in the pole motion from data on the angular momenta of the atmosphere and the ocean. The oceanic and the atmospheric excitations account for about 65–70% of the dispersion of the observed pole motion.
