Surface Wave Isotropic and Azimuthally Anisotropic Dispersion across Alaska and the Alaska-Aleutian Subduction Zone

This dataset is supplementary to C. Liu, S. Zhang, A.F. Sheehan, M.H. Ritzwoller, Surface Wave Isotropic and Azimuthally Anisotropic Dispersion across Alaska and the Alaska-Aleutian Subduction Zone (2022) This dataset contains: 1) AK_Ray_azimap_8_85s_update.txt: the updated composite Rayleigh wave isotropic phase velocity and azimuthal anisotropy maps from 8 to 85 s both onshore and offshore on a 0.2°×0.1° grid 2) AK_Lov_isomap_8_80s.txt: the composite Love wave isotropic phase velocity maps from 8 to 80 s onshore on a 0.2°×0.1° grid (same as V1.0) P.S. Please check V1.0 page for stacked three-station interferograms (SAC_I3_stacked_AK.zip, SAC format)本数据集为C. Liu、S. Zhang、A.F. Sheehan、M.H. Ritzwoller等人所著《阿拉斯加及阿拉斯加-阿留申俯冲带面波各向同性与方位各向异性弥散》（Surface Wave Isotropic and Azimuthally Anisotropic Dispersion across Alaska and the Alaska-Aleutian Subduction Zone, 2022）的补充数据集。本数据集包含以下内容：1) AK_Ray_azimap_8_85s_update.txt：更新后的复合瑞利波（Rayleigh wave）各向同性相速度与方位各向异性分布图，周期范围为8至85秒，覆盖陆上与海域，网格分辨率为0.2°×0.1°；2) AK_Lov_isomap_8_80s.txt：复合勒夫波（Love wave）各向同性相速度分布图，周期范围为8至80秒，仅覆盖陆上区域，网格分辨率为0.2°×0.1°（与V1.0版本一致）。附注：请查阅V1.0版本页面以获取堆叠式三台站干涉图（SAC_I3_stacked_AK.zip，SAC格式（SAC format））。
