Formula for the Chandler Period (Free Wobble of Planetary Bodies)
Geophysical Research LettersIf the rotational equilibrium of a planetary body is disturbed, the rotation pole responds with a cyclical motion. The duration of one cycle is referred to as the Chandler period, and, when viewed from space, the body wobbles.

Measuring chandler wobble amplitude variations using IERS EOP C04 data [PDF]
Serbian Astronomical Journal, 2023 We analyzed the Earth's long-term polar motion using the time series IERS EOP C04 (International Earth Rotation and Reference Systems Service - IERS; Earth Orientation Parameters - EOP; Combination of four (04) techniques - C04), from 1984 to ...

Analysis of 25 Years of Polar Motion Derived from the DORIS Space Geodetic Technique Using FFT and SSA Methods [PDF]
Sensors, 2020 Polar motion (PM) has a close relation to the Earth’s structure and composition, seasonal changes of the atmosphere and oceans, storage of waters, etc.

Variations of seismic activity caused by the Chandler Wobble [PDF]
E3S Web of Conferences, 2019 The problem of the correlation of the global dynamic phenomenon “Chandler wobble” with the local dynamics in different parts of the Earth’s crust and lithosphere is wide of the solution.

Preliminary tide gauge evidence for equilibrium and non-equilibrium pole tide variability after the 2015 Chandler Wobble amplitude reduction [PDF]
Earth, Planets and SpaceThe pole tide has been defined as the oceanic response to polar motion, with a component due to the Chandler Wobble (CW), at a period near 14 months. The magnitude of the CW was greatly reduced after about 2015, and a corresponding global attenuation of ...

Determining the moment of inertia of triaxial Mars with updated global gravity models
Earth and Planetary Physics, 2023 The principal moments of inertia (PMIs) with the principal axes are usually taken as the dynamic figure parameters of Mars; they can be deduced from satellite-observed degree-two gravitational potentials in recent global gravity models and from the ...

Polyphony of Short-Term Climatic Variations
Atmosphere, 2021 It is widely accepted to believe that humanity is mainly responsible for the worldwide temperature growth during the period of instrumental meteorological observations. This paper aims to demonstrate that it is not so simple.

Geodesy and Geodynamics, 2020 Until now, the calculation of the principal inertia moment of the triaxial three-layered Earth mainly adopts the scaling method. This method assumes that the corresponding principal inertia axes of the layers coincide each other, but this is not the case.

Chandler wobble excitation by catastrophic flooding of the Black Sea
Annals of Geophysics, 1999 It is now widely accepted that during the late Quaternary glaciation the Black Sea formed an isolated inland lake (Ross et al., 1970). New geological data and the recognition of sudden population movements away from the Black Sea coasts suggest that the ...
