Prograde and Retrograde Terms of Gravimetric Polar Motion Excitation Estimates from the GRACE Monthly Gravity Field Models

open access: yesRemote 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).

OSCILLATIONS OF DRY AIR IN THE ATMOSPHERE

open access: yesНаука. Инновации. Технологии, 2022
Introduction. The article examines the influence of the terrain and the daily rotation of the Earth on the oscillatory processes in the atmosphere. It is shown that as a result of the superposition of two oscillatory processes, caused both by natural ...

Contribution of CRUST2.0 components to the tri-axiality of the Earth and equatorial flattening of the core

open access: yesGeodesy and Geodynamics, 2013
Equatorial flattening of the core were previously estimated to be 5 × 10−4 by using seismically derived density anomaly, and 1.7748280 × 10−5 by assuming that the ratio of polar flattening to equatorial flattening of the core is the same as that of the ...

Long-period nutational-precessional motions of the instantaneous Earth rotation pole

open access: yesУчёные записки Казанского университета: Серия Физико-математические науки, 2020
The influence of the rotational regime on real long-period nutational-precessional motions of the instantaneous pole of the Earth’s rotation is considered. The solar magnetospheric (through changes in the angular velocity of rotation) mechanism of action

Formation Design for Single-Pass GEO InSAR Considering Earth Rotation Based on Coordinate Rotational Transformation

open access: yesRemote Sensing, 2020
The single-pass geosynchronous synthetic aperture radar interferometry (GEO InSAR) adopts the formation of a slave satellite accompanying the master satellite, which can reduce the temporal decorrelation caused by atmospheric disturbance and observation ...
