Validation of GRACE and GRACE-FO Mascon Data for the Study of Polar Motion Excitation
Remote Sensing, 2021 In this study, we calculate the hydrological plus cryospheric excitation of polar motion (hydrological plus cryospheric angular momentum, HAM/CAM) using mascon solutions based on observations from the Gravity Recovery and Climate Experiment (GRACE) and ...

Short periodic variations of polar motion and hemispheric atmospheric angular momentum excitation functions in the period 1984-1992 [PDF]
Annales Geophysicae, 1995 Short periodic oscillations with the periods from 10 up to 110 days of the hemispheric components of effective atmospheric angular momentum (EAAM) excitation function and their correlation with polar motion excitation function have been analyzed.

Atmospheric excitation of polar motion
Geo-Spatial Information Science, 2010 The polar motion excited by the fluctuation of global atmospheric angular momentum (AAM) is investigated. Based on the global AAM data, numerical results demonstrate that the fluctuation of AAM can excite the seasonal wobbles (e.g., the 18-month wobble) and the Chandler wobble, which agree well with previous studies.

Remote Sensing, 2019 This study evaluates the gravity field solutions based on high-low satellite-to-satellite tracking (hl-SST) of low-Earth-orbit (LEO) satellites: GRACE, Swarm, TerraSAR-X, TanDEM-X, MetOp-A, MetOp-B, and Jason 2, by converting them into hydrological polar

Remote Sensing, 2020 From 2002 to 2017, the Gravity Recovery and Climate Experiment (GRACE) mission’s twin satellites measured variations in the mass redistribution of Earth’s superficial fluids, which disturb polar motion (PM).

Excitation of annual polar motion by atmosphere and ocean
Science Bulletin, 2000 The quantitative result of annual polar motion excitation by the ocean is presented for the first time. The atmospheric excitation amounts to more than double of the oceanic excitation. The sum of atmospheric and oceanic excitations approximates more to the observed annual polar motion excitation, compared with atmospheric excitation only.

Geodetic residual time series: A combined series by minimization of their internal noise level
Frontiers in Earth Science, 2023 This study aims to assess the hydrological effects of polar motion calculated from different combinations of geophysical excitations at decadal, seasonal, and non-seasonal periods.
