Abstract. We use seismic waveform data from the AlpArray Seismic Network and three other temporary seismic networks, to perform receiver function (RF) calculations and time-to-depth migration to update the knowledge of the Moho discontinuity beneath the broader European Alps. In particular, we set up a homogeneous processing scheme to compute RFs using the time-domain iterative deconvolution method and apply consistent quality control to yield 112 205 high-quality RFs. We then perform time-to-depth migration in a newly implemented 3D spherical coordinate system using a European-scale reference P and S wave velocity model. This approach, together with the dense data coverage, provide us with a 3D migrated volume, from which we present migrated profiles that reflect the first-order crustal thickness structure. We create a detailed Moho map by manually picking the discontinuity in a set of orthogonal profiles covering the entire area. We make the RF dataset, the software for the entire processing workflow, as well as the Moho map, openly available; these open-access datasets and results will allow other researchers to build on the current study.

欧洲阿尔卑斯山下的莫霍面深度：均匀处理的地图和接收函数数据库

摘要。我们使用来自 AlpArray 地震台网和其他三个临时地震台网的地震波形数据来执行接收函数 (RF) 计算和时间深度偏移，以更新更广泛的欧洲阿尔卑斯山下莫霍面的知识。特别是，我们建立了一个齐次处理方案来使用时域迭代反卷积方法计算 RF，并应用一致的质量控制来产生 112 205 个高质量的 RF。然后，我们使用欧洲尺度参考 P 和 S 波速度模型在新实施的 3D 球坐标系中执行时间深度偏移。这种方法与密集的数据覆盖一起，为我们提供了一个 3D 偏移量，我们从中展示了反映一阶地壳厚度结构的偏移剖面。我们通过手动选择一组覆盖整个区域的正交剖面中的不连续点来创建详细的莫霍面图。我们公开了射频数据集、整个处理流程的软件以及莫霍面图；这些开放获取的数据集和结果将允许其他研究人员在当前研究的基础上进行构建。
