Geophysics From Terrestrial Time‐Variable Gravity Measurements
In a context of global change and increasing anthropic pressure on the environment, monitoring the Earth system and its evolution has become one of the key missions of geosciences. Geodesy is theExpand
Evidence of Earthquake Triggering by the Solid Earth Tides
article i nfo Clearevidence forearthquake triggeringbythe earth tides hasremained elusive for morethan a century.Using the largest global earthquake catalog available (the NEIC catalog with 442412Expand
Coseismic and post-seismic signatures of the Sumatra 2004 December and 2005 March earthquakes in GRACE satellite gravity
S U M M A R Y The GRACE satellite mission has been measuring the Earth's gravity field and its temporal variations since 2002 April. Although these variations are mainly due to mass transfer withinExpand
Repeated absolute gravity measurements for monitoring slow intraplate vertical deformation in western Europe
In continental plate interiors, ground surface movements are at the limit of the noise level and close to or below the accuracy of current geodetic techniques. Absolute gravity measurements areExpand
Optimized strategy for the calibration of superconducting gravimeters at the one per mille level
This paper reports on different sources of errors that occur in the calibration process of a superconducting gravimeter (SG), determined by comparison with a ballistic absolute gravimeter (AG); someExpand
Constraints on the coupling at the core-mantle and inner core boundaries inferred from nutation observations
SUMMARY We present an inversion of nutation observations in terms of parameters characterizing the Earth’s interior properties. We use a Bayesian inversion in the time-domain, allowing us to takeExpand
Characterization and implications of intradecadal variations in length of day
Variations in Earth's rotation (defined in terms of length of day) arise from external tidal torques, or from an exchange of angular momentum between the solid Earth and its fluid components. OnExpand
Estimation of Earth interior parameters from a Bayesian inversion of very long baseline interferometry nutation time series
[1] Among the variations in the rotation of the Earth, the nutation is the most suitable for studying the Earth's internal structure. The nutation is mainly driven by the gravitational torque of theExpand
Separating climate‐induced mass transfers and instrumental effects from tectonic signal in repeated absolute gravity measurements
We estimate the signature of the climate-induced mass transfers in repeated absolute gravity measurements based on satellite gravimetric measurements from the Gravity Recovery and Climate ExperimentExpand
Atmospheric torque on the Earth and comparison with atmospheric angular momentum variations
The purpose of this paper is to compute atmospheric torques on the Earth, including the oceans, with an emphasis on the equatorial components. This dynamic approach is an alternative method to theExpand
