Supporting GPR Data for Time-Lapse Imaging of Subsurface Fluid Heterogeneity With Physics-Guided Diffusion-Regularized Full-Waveform Inversion

Abstract

This dataset provides the supporting ground penetrating radar data used for laboratory and field validation in the study “Time-Lapse GPR Imaging of Subsurface Fluid Heterogeneity With Physics-Guided Diffusion-Regularized Full-Waveform Inversion.” The deposited files contain the data required to support the real data analyses and corresponding figures reported in the manuscript, including measurements from the controlled non aqueous phase liquid tank experiment and selected field observations from a karst environment. The dataset is provided to support transparency, reproducibility, and independent evaluation of the results presented in the associated study. It represents the subset of experimental and field data directly underlying the analyses reported in the manuscript and does not constitute the complete archive from the broader laboratory and field campaigns. Supporting source code, computational notebooks, and trained diffusion model weights are archived separately on Zenodo and in the associated GitHub repository.
