The numerical prediction of the Earth’s polar motion based on an advanced multivariate algorithm
Frontiers in Astronomy and Space Sciences, 2023 Since there are complicated changes in the polar motion (PM) from sub-annual to decadal, precisely predicting it is challenging. Here, we provide an advanced multivariate algorithm by combining an iterative oblique singular spectrum analysis (IOSSA) with

Improvement of the prediction accuracy of polar motion using empirical mode decomposition
Geodesy and Geodynamics, 2017 Previous studies revealed that the error of pole coordinate prediction will significantly increase for a prediction period longer than 100 days, and this is mainly caused by short period oscillations.

Long-term polar motion prediction using normal time–frequency transform [PDF]
Journal of Geodesy, 2013 This paper presents normal time–frequency transform (NTFT) application in harmonic/quasi-harmonic signal prediction. Particularly, we use the normal wavelet transform (a special NTFT) to make long-term polar motion prediction. Instantaneous frequency, phase and amplitude of Chandler wobble, prograde and retrograde annual wobbles of Earth’s polar motion
