A new polar motion prediction method combined with the difference between polar motion series
Geodesy and Geodynamics, 2022 After the first Earth Orientation Parameters Prediction Comparison Campaign (1st EOP PCC), the traditional method using least-squares extrapolation and autoregressive (LS + AR) models was considered as one of the polar motion prediction methods with ...

Secular polar motion observed by GRACE. [PDF]
J Geod, 2021 AbstractA long-term drift in polar motion (PM) has been observed for more than a century, and Glacial Isostatic Adjustment (GIA) has been understood as an important cause. However, observed PM includes contributions from other sources, including contemporary climate change and perhaps others associated with Earth’s interior dynamics.

Kimura’s contributions on Earth polar motion studies [PDF]
Proceedings of the Japan Academy. Series B, Physical and Biological SciencesKimura’s discovery of z-term in the polar motion (Astron. J. 22, 107 (1902) and Astron. Nachr. 158, 233 (1902)) was recognized as an epoch-making scientific achievement for modern Japan, opening its doors to the world in 1868.

Climate‐Induced Polar Motion: 1900–2100
Geophysical Research LettersIt has been demonstrated that the motion of the Earth's rotational pole with respect to the crust—termed polar motion—is increasingly influenced by barystatic processes, that is, continental‐ocean mass redistribution due to melting of polar ice sheets ...

Estimation of the Parameters of the Earth’s Polar Motion [PDF]
Symposium - International Astronomical Union, 1979 The parameters of the Earth's polar motion have been estimated by a method which accounts for observational error and which treats two possible statistical models for the polar motion excitation process. Both a 100 year and a 78 year long polar motion series have been used to estimate the Chandler wobble frequency, Fc, and quality factor, Qc; the noise

Electroencephalography Enables Continuous Decoding of Hand Motion Angles in Polar Coordinates [PDF]
Cyborg and Bionic SystemsHand movements in task space are typically represented using either Cartesian or polar coordinate systems. While Cartesian coordinates are commonly used in electroencephalography (EEG)-based brain–computer interface (BCI) studies, polar coordinates offer
