This dataset contains the short-period Rayleigh wave ellipticity (4 - 8 s in period) measured from continuous waveforms of seismic ambient noise recorded by 3848 seismic stations deployed in continental China during 1990 and 2017. This dataset results from a project of constructing a 3-D seismic model of the shallow crust in continental China (Xiao et al, 2021, GJI) (model link). 本数据库包含了利用1990 至 2017 年间中国大陆区域地震台站记录的连续背景噪声波形测量得到的短周期瑞利波偏振( 周期 4 - 8 s )。该数据库源于构建中国大陆区域高精度浅层地壳三维地震学模型的工作 (Xiao et al, 2021, GJI) (模型链接) 。 If you face any problem or issue in the usage of this dataset, please feel free to communicate with the corresponding author Xiao Xiao (xiaox.seis@gmail.com).
