Longterm Shear Wave Splitting Measurements in the Upper Rhine Graben Area

This dataset contains shear wave splitting measurements (SWSMs) on SKS, SKKS, and PKS phases at the (semi-) permanent broadband seismological recording stations Black Forest Observatory (BFO), Welschbruch (WLS), Stuttgart (STU), Échery (ECH), Karlsruhe-Durlach (TMO44), and KIT-GPI (TMO07). Splitting parameters (fast polarization direction and delay time) were obtained with the MATLAB package SplitLab (Wüstefeld et al. 2008) simultaneously applying the rotation-correlation method (Bowman & Ando 1987) and the energy minimization method (Silver & Chan 1991). Additionally, the splitting intensity (Chervot 2000) is reported. Only single-event analysis SWSMs of good and fair qualities are reported. Information of the used earthquakes are included. CSV as well as PDF files are provided. Details can be found in the README. The dataset is related to the publication Fröhlich et al. (2024), GJI, https://doi.org/10.1093/gji/ggae245.

本数据集包含针对SKS、SKKS及PKS震相的横波分裂测量（shear wave splitting measurements, SWSMs）数据，采集自半永久/永久宽带地震台站：黑森林观测台（Black Forest Observatory, BFO）、韦尔施布鲁赫台（Welschbruch, WLS）、斯图加特台（Stuttgart, STU）、埃谢里台（Échery, ECH）、卡尔斯鲁厄-迪拉赫台（Karlsruhe-Durlach, TMO44）以及KIT-GPI台（TMO07）。横波分裂参数（快波偏振方向与延迟时间）通过MATLAB工具包SplitLab（Wüstefeld等，2008）获取，同时采用旋转相关法（Bowman & Ando, 1987）与能量最小化法（Silver & Chan, 1991）两种方法。此外，本数据集还报告了分裂强度（Chervot, 2000）相关结果。仅收录质量等级为良好与一般的单事件横波分裂测量数据，同时包含所用地震的相关信息。数据集提供CSV与PDF两种格式的文件，详细说明可参阅数据集附带的README文档。本数据集关联Fröhlich等人（2024）发表于《国际地球物理期刊》（GJI）的研究成果，DOI链接为https://doi.org/10.1093/gji/ggae245。
