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

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.

Probabilistic approach to Gramian inversion of multiphysics data
Frontiers in Earth Science, 2023 We consider a probabilistic approach to the joint inversion of multiphysics data based on Gramian constraints. The multiphysics geophysical survey represents the most effective technique for geophysical exploration because different physical data reflect

Geostatistical joint inversion of frequency-domain electromagnetic data and direct current resistivity data for near-surface modelling. [PDF]
Sci RepGeophysical 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 ...
