Remote Sensing, 2022 Observations from the Gravity Recovery and Climate Experiment (GRACE) and GRACE Follow-On (GRACE-FO) missions can be used to estimate gravimetric excitation of polar motion (PM), which reflects the contribution of mass changes in continental hydrosphere ...

Theory of cavity-assisted microwave cooling of polar molecules [PDF]
, 2008 We analyze cavity-assisted cooling schemes for polar molecules in the microwave domain, where molecules are excited on a rotational transition and energy is dissipated via strong interactions with a lossy stripline cavity, as recently proposed by A ...

Geodesy and Geodynamics, 2017 At seasonal and intraseasonal time scales, polar motions are mainly excited by angular momentum fluctuations due to mass redistributions and relative motions in the atmosphere, oceans, and continental water, snow, and ice, which are usually provided by ...

Polar ionospheric responses to solar wind IMF changes [PDF]
Annales Geophysicae, 2000 Auroral and airglow emissions over Eureka (89° CGM) during the 1997-98 winter show striking variations in relation to solar wind IMF changes. The period January 19 to 22, 1998, was chosen for detailed study, as the IMF was particularly strong and ...

Remote Sensing, 2022 Due to the conservation of global angular momentum, polar motion (PM) is dominated by global mass redistributions and relative motions in the atmosphere, oceans and land water at seasonal time scales.

Scattering of particles by neutron stars: Time-evolutions for axial perturbations [PDF]
, 2000 The excitation of the axial quasi-normal modes of a relativistic star by scattered particles is studied by evolving the time dependent perturbation equations.

Mass-related excitation of polar motion: an assessment of the new RL06 GRACE gravity field models
Earth, Planets and Space, 2018 The new Release-06 (RL06) Gravity Recovery and Climate Experiment (GRACE) gravity field solutions are evaluated by converting them into equatorial effective angular momentum functions (so-called excitation functions) for polar motion and comparing these ...

Geophysical Research Letters, 2023 Climate model estimates show significant groundwater depletion during the 20th century, consistent with global mean sea level (GMSL) budget analysis. However, prior to the Argo float era, in the early 2000’s, there is little information about steric sea ...

Hydrological Excitation of Polar Motion Derived from GRACE Gravity Field Solutions
International Journal of Geophysics, 2011 The influence of the continental water storage on the polar motion is not well known. Different models have been developed to evaluate these effects and compared to geodetic observations.

Comment [on “Polar motions excited by a convecting viscous mantle”] [PDF]
Geophysical Research Letters, 1993 Abstract In the last few years there has been a renewed interest in the problem of true polar wander (TPW) induced by slowly varying mass redistribution. Moser et al.,(1992) disagrees with our own results, Ricard et. al.(1992) on three different points:(1) The amplitude of the non-diagonal inertia perturbations that should be considered;(2) The ...
