Data and source files for "Strategies for Correcting Nonstationary Resistivity–Water Content Relations in Time-Lapse ERT"

This dataset contains source data and processed outputs supporting the manuscript “Strategies for Correcting Nonstationary Resistivity–Water Content Relations in Time-Lapse ERT”. The manuscript evaluates strategies for correcting nonstationary resistivity–water content relations in time-lapse electrical resistivity tomography (ERT). The archived materials include figure source data for the main and supplementary figures, processed datasets used for stationary petrophysical modelling, data-assimilation outputs, machine-learning prediction outputs, and model-performance summaries. The dataset is intended to support transparency and reproducibility of the manuscript results. It provides the data required to reproduce the figures and key quantitative comparisons reported in the paper. Raw or selected input data, processed data tables, figure source files, and documentation are organised by figure and analysis component. This record will be updated with the final manuscript citation after publication.
