CSRM Level 2 dataset: Rayleigh wave phase and group velocity maps in continental China

<p>This dataset contains the Rayleigh wave phase/group velocity maps at the period range from 8&nbsp; to 70 s. These maps are obtained by travel time tomography using the <strong>639,171</strong> inter-station and <strong>54,792 </strong>event-station Rayleigh wave phase/group velicity dispersion curves (<a href="../records/8103561">data link</a>). The spatial resolution of these maps is ~60 km in the north-south seismic belt and thans-North China Orogen regions, and ~120 km in the rest of the continental China. This dataset results from a project of constructing the high-resolution China Seismological Reference Model (<strong>CSRM-1.0</strong>) in the top 100 km of the crust and uppermost mantle in continental China (<a href="https://doi.org/10.1029/2024JB029520">Xiao et al, JGR, 2024</a>) (<a href="https://doi.org/10.5281/zenodo.11098135">model link</a>).</p> <p>本数据库包含了利用 <strong>8 - 70 s </strong>的中国大陆区域瑞利波相/群速度结构。反演该相/群速度结构用到了&nbsp;<strong>639,171&nbsp;</strong>条台站间瑞利波相/群速度频散曲线和 <strong>54,792 </strong>事件-台站间频散曲线(数据链接)。相/群速度图在南北地震带和华北造山带的分辨率约为 <strong>60</strong> km, 在中国大陆其他区域的分辨率约为 <strong>120</strong> km。该数据库源于构建中国大陆区域高精度地壳和上地幔顶部 100 公里三维地震学模型(<strong>CSRM-1.0</strong>)的工作 (<a href="https://doi.org/10.1029/2024JB029520">Xiao et al, JGR, 2024</a>) (<a href="https://doi.org/10.5281/zenodo.11098135">模型链接</a>) 。</p> <p>If you face any problem or issue in the usage of this dataset, please feel free to communicate with the corresponding author Xiao Xiao&nbsp;(<strong>xiaox.seis@gmail.com</strong>).&nbsp;</p>
