Separation of coseismic and postseismic gravity changes for the 2004 Sumatra–Andaman earthquake from 4.6 yr of GRACE observations and modelling of the coseismic change by normal-modes summation
eodSpatiale (GRGS). For comparison, the Release-04 solutions of the Center for Space Research (CSR) are also inves- tigated after a spectral windowing or a Gaussian spatial smoothing. Results areExpand
Gravimetric Methods – Superconducting Gravity Meters
This chapter is devoted to the superconducting gravimeter (SG) and its wide use in Earth sciences. The first part is merely instrumental: the history of the technical developments is first givenExpand
GPS and gravity constraints on continental deformation in the Alborz mountain range, Iran
A network of 54 survey GPS sites, 28 continuous GPS stations and three absolute gravity (AG) observation sites have been set up in the Alborz mountain range to quantify the present-day kinematics ofExpand
A search for the ratio between gravity variation and vertical displacement due to a surface load
SUMMARY We study the ratio between the gravity variation and vertical displacement at the surface of a self-gravitating spherical elastic earth model when a load is applied at the surface. ByExpand
Network of superconducting gravimeters benefits a number of disciplines
A global network of superconducting gravimeters (SGs) is compiling significant data for a range of important studies spanning a number of disciplines concerned with the Earth's gravity, tides,Expand
GPS measurements of ocean loading and its impact on zenith tropospheric delay estimates: a case study in Brittany, France
Abstract. The results from a global positioning system (GPS) experiment carried out in Brittany, France, in October 1999, aimed at measuring crustal displacements caused by ocean loading andExpand
Study of the seasonal gravity signal in superconducting gravimeter data
Thanks to their high sensitivity and their long-term stability, superconducting gravimeters (SG) are able to record surface gravity changes on a wide frequency band (periods from a few seconds toExpand
Analysis of a 10-year (1997–2007) record of time-varying gravity in Strasbourg using absolute and superconducting gravimeters: New results on the calibration and comparison with GPS height changes
Abstract This paper is devoted to a detailed investigation of a continuous record spanning more than 10 years (1997–2007) of the Strasbourg superconducting gravimeter (SG GWR C026). We show theExpand
Effective barometric admittance and gravity residuals
Abstract In the analysis of surface gravity signals that may originate from the Earth's core, the step of correcting for the atmospheric pressure fluctuations is one that must be done carefully. WeExpand
Stacking gravity tide measurements and nutation observations in order to determine the complex eigenfrequency of the nearly diurnal free wobble
The resonance due to the nearly diurnal free wobble, observed in the diurnal tesseral tides and in the associated nutations, is used to determine the frequency and the damping of this wobble. TheExpand
