Observation of the variations in the Earth's rotation at time scales ranging from subdiurnal to
multidecadal allows us to learn about its deep interior structure. We review all three types of …

Intradecadal changes in GPS displacements have garnered significant attention within the
research community; however, the existence of relatively stable intradecadal signals, as well …

We carefully reanalyze the∼ 6-yr oscillation (SYO), which has been previously found in the
Earth's length of day variation (ΔLOD) and has been considered important for understanding …

The intradecadal variations in length-of-day (LOD) and their time-varying characteristics still
need to be further studied. Given that the corresponding signal periods on the intradecadal …

To advance geodynamics and geophysical research, high precision Global Navigation
Satellite System (GNSS) observations of velocity and position are needed. In this study, we …

The intradecadal fluctuations in the length‐of‐day variation (∆ LOD) are considered likely to
play an important role in core motions. Two intradecadal oscillations, with∼ 5.9 and∼ 8.5 …

The Earth's oblateness varies slightly due to a host of physical processes that involve large‐
scale meridional N‐S mass redistributions in the Earth. We analyze these minute …

Surface and deep potential geophysical signals respond to the spatial redistribution of
global mass variations, which may be monitored by geodetic observations. In this study, we …

The multidecadal fluctuations in sea level changes play an important role in the exact
quantification of present‐day global mean sea level (GMSL) rise and its acceleration. Here …

To analyze quasi‐periodic signals (with time‐varying complex amplitudes/frequencies)
typically contained in geophysical observables is a quest that has seen continual advances …
