我们提供了来自加利福尼亚州垂直阵列站点的地面运动记录和站点信息的数据集。记录包括地面震动和井下传感器的两个水平分量。同一地点的地面和井下记录的可用性有助于直接观察现场响应。现场数据包括测量的剪切波和压缩波速度，以及岩土钻孔日志（如果有）。我们考虑了加利福尼亚州的 39 个垂直阵列站点，并根据至少有四对地面/井下记录选择了 21 个纳入数据库。记录和现场数据显示在数据存储库中，可通过 DesignSafe 平台访问（DOI：10.17603/146DS2N680）。原始数字加速度图的处理方式与 NGA-West2 协议一致。在本文中，该数据集与其他人编译的来自日本垂直阵列的类似但更大的数据集进行了比较。
We present a data set of ground motion recordings and site information from vertical array sites in California. The recordings include two horizontal components of ground shaking at the ground surface level and from downhole sensors. The availability of both surface and downhole recordings at the same site facilitates direct observations of site response. The site data include measured shear-and compression-wave velocities, and, where available, geotechnical boring logs. We considered 39 vertical array sites in California and chose 21 for inclusion in the database on the basis of having at least four pairs of surface/downhole recordings. The recordings and site data are presented in a data repository, which is accessible at the DesignSafe platform (DOI: 10.17603/146DS2N680). The original digital accelerograms are processed in a manner consistent with NGA-West2 protocols. In this paper, this data set is compared to a similar but larger data set from Japanese vertical arrays compiled by others.
