A synthetic 3D ground-penetrating radar (GPR) data set across a realistic sedimentary model

______V1____________2019____________________
This data set includes a 3D modeled ground-penetrating radar (GPR) reflection data set as well as the underlying realistic sedimentary model.

We provide a 3D porosity model showing heterogeneities down to the sub-facies scale. We have inferred this model from the publicly available 3D Herten hydrofacies model ('Realization 1' in Supplementary Material of Comunian et al., 2011; see related links down below) and the associated porosity values and ranges (Bayer et al., 2011; see related links down below). Details on the generation of our porosity model are found in the associated article.
We deliver our unprocessed 3D GPR reflection data set modeled using gprMax (Warren et al., 2016; see related links down below) across the entire model surface assuming fresh-water saturated sediments. Details on the transformation of the porosity model into electrical parameter fields used as input for GPR modeling as well as information on the GPR modeling procedure are found in the associated article.

Additionally, we provide basic code to read and visualize the provided data in MATLAB and python. The Readme-file comprises detailed descriptions of the data files and formats and step-by-step instructions on code usage and ParaView visualization.

本数据集包含一套三维建模的探地雷达（ground-penetrating radar, GPR）反射数据集，以及对应的真实沉积模型。

我们提供了一套可展现亚相尺度非均质性的三维孔隙度模型。该模型基于公开可用的三维Herten水成相模型（取自Comunian等人2011年补充材料中的‘实现1’；详见下文相关链接）以及对应的孔隙度数值与取值范围（Bayer等人2011年；详见下文相关链接）推演得到。关于本孔隙度模型的生成细节，请参阅相关研究论文。

我们提供了未经处理的三维GPR反射数据集，该数据集基于淡水饱和沉积物假设，使用gprMax（Warren等人2016年；详见下文相关链接）在整个模型表面上进行建模。关于将孔隙度模型转换为GPR建模所需的电性参数场的细节，以及GPR建模流程的相关信息，请参阅相关研究论文。

此外，我们提供了用于在MATLAB与Python中读取并可视化所提供数据的基础代码。README文件包含了数据文件与格式的详细说明，以及代码使用与ParaView可视化的分步指南。
