S U M M A R Y The appraisal of tomographic models, of fundamental importance towards better understanding the Earth’s interior, consists in analysing their resolution and covariance. The discrete theory of Backus–Gilbert, solving all at once the linear problems of model estimation and appraisal, aims at evaluating weighted averages of the true model parameters. Contrary to damped least-squares techniques, one key advantage of Backus–Gilbert inversion is that no subjective regularization is…

S U M M A R Y This proof-of-concept study presents a parameter-free, linear Backus–Gilbert inversion scheme, tractable for seismic tomography problems. It leads to efficient computations of unbiased
Optimal resolution tomography with error tracking and the structure of the crust and upper mantle beneath Ireland and Britain
The classical Backus–Gilbert method seeks localized Earth-structure averages at the shortest length scales possible, given a data set, data errors, and a threshold for acceptable model errors. The
Tomographic filtering via the generalized inverse: a way to account for seismic data uncertainty
Tomographic-geodynamic model comparisons are a key component in studies of the present-day state and evolution of Earth’s mantle. To account for the limited seismic resolution, ‘tomographic
The Dulmage–Mendelsohn permutation in seismic tomography
Seismic tomography inverse problems are among the largest high-dimensional parameter estimation tasks in Earth science. Although iterative algorithms can be used to efficiently solve these problems,
Toward Seeing the Earth's Interior Through Unbiased Tomographic Lenses
Geophysical tomographic studies traditionally exploit linear, damped least squares inversion methods. We demonstrate that the resulting models can be locally biased toward lower or higher amplitudes
SubMachine: Web‐Based Tools for Exploring Seismic Tomography and Other Models of Earth's Deep Interior
A collection of web‐based tools for the interactive visualization, analysis, and quantitative comparison of global‐scale data sets of the Earth's interior, which focuses on making regional and global-scale seismic tomography models easily accessible to the wider solid Earth community.
Seismic evidence for partial melt below tectonic plates.
Partial melt occurring within the seismic low-velocity zone is reported on the basis of the interpretation of global three-dimensional shear attenuation and velocity models, suggesting that by reducing viscosity melt facilitates plate motion and large-scale crystal alignment in the asthenosphere.
Rayleigh wave group velocity dispersion tomography of West Africa using regional earthquakes and ambient seismic noise
West Africa could teach us much about the early tectonic history of Earth, but current seismic models of the regional crustal and lithospheric structure lack the resolution required to answer all but
Trans‐Dimensional Surface Reconstruction With Different Classes of Parameterization
The use of Bayesian trans‐dimensional sampling in 2‐D and 3‐D imaging problems has recently become widespread in geophysical inversion. Its benefits include its spatial adaptability to the level of
Local Estimation of the Earth's Core Magnetic Field
The geomagnetic field is generated in the Earth’s outer core by fluid motions in a process known as the geodynamo. During the past 18 years satellite magnetic measurements have provided new insights


On the use of sensitivity tests in seismic tomography
Sensitivity analysis with synthetic models is widely used in seismic tomography as a means for assessing the spatial resolution of solutions produced by, in most cases, linear or iterative nonlinear
Global seismic tomography: the inverse problem and beyond
Global seismic tomography has produced a great amount of robust information concerning the three-dimensional extent of the Earth's internal structure. This has stimulated a multidisciplinary
Joint inversion of normal-mode and finite-frequency S-wave data using an irregular tomographic grid

Measures of resolution in global body wave tomography
