Description

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)
