Geostatistical joint inversion of frequency-domain electromagnetic data and direct current resistivity data for near-surface modelling [PDF]
Scientific ReportsGeophysical methods, such as electrical resistivity tomography (ERT) and frequency-domain electromagnetic (FDEM) induction, have been widely used for imaging and modelling the first meters of the Earth, in fields like agriculture, urban development ...

Selection of borehole temperature depth profiles for regional climate reconstructions [PDF]
Climate of the Past, 2007 Borehole temperature depth profiles are commonly used to infer time variations in the ground surface temperature on centennial time scales. We compare different procedures to obtain a regional ground surface temperature history (GSTH) from an ensemble of

Joint geoacoustic inversion based on Pearson correlation coefficient constraints [PDF]
JASA Express Letters, 2023 This Letter proposes a joint geoacoustic inversion method for modal group velocity dispersion and amplitudes of waveform by incorporating a Pearson correlation constraint. Numerical simulations show that this joint inversion leads to improved geoacoustic

Joint migration inversion: features and challenges [PDF]
Journal of Geophysics and Engineering, 2020 Abstract Joint migration inversion is a recently proposed technology, accommodating velocity model building and seismic migration in one integrated process. Different from the widely accepted full waveform inversion technology, it uses imaging parameters, i.e.

Joint Sampling and Optimisation for Inverse Rendering
SIGGRAPH Asia 2023 Conference Papers, 2023 When dealing with difficult inverse problems such as inverse rendering, using Monte Carlo estimated gradients to optimise parameters can slow down convergence due to variance. Averaging many gradient samples in each iteration reduces this variance trivially. However, for problems that require thousands of optimisation iterations, the computational cost

Geodesy and Geodynamics, 2023 Joint inversion is one of the most effective methods for reducing non-uniqueness for geophysical inversion. The current joint inversion methods can be divided into the structural consistency constraint and petrophysical consistency constraint methods ...

Consistent retrieval of land surface radiation products from EO, including traceable uncertainty estimates [PDF]
Biogeosciences, 2017 Earth observation (EO) land surface products have been demonstrated to provide a constraint on the terrestrial carbon cycle that is complementary to the record of atmospheric carbon dioxide.
