Seismic radial and azimuthal anisotropy tomography beneath Greenland and surrounding regions

Dear readers,

These four files contain P-wave velocity model beneath Greenland and surrounding regions obtained by regional anisotropy tomography (Toyokuni & Zhao, 2021, ESS). 

P-wave radial anisotropy (RAN) model
RAN_DV0.DAT: Isotropic component (DV0) of RAN tomography
-FORMAT: Latitude(deg), Longitude(deg), Depth(km), dVp0(%)

RAN_AI.DAT: Anisotropic component RAN tomography
-FORMAT: Longitude(deg), Latitude(deg), Depth(km), alpha(%)

P-wave azimuthal anisotropy (AAN) model
AAN_DV0.DAT: Isotropic component (DV0) of AAN tomography
-FORMAT: Latitude(deg), Longitude(deg), Depth(km), dVp0(%)

AAN_AI.DAT: Anisotropic component AAN tomography
-FORMAT: Longitude(deg), Latitude(deg), Depth(km), FVD(deg), beta(%)

We note that the tomography was conducted in the transformed coordinates. The details of the coordinate transformation are described in the above paper. We also note that the fast velocity direction (FVD) of the AAN model is in the transformed coordinates. Please contact us if you want any program to convert it back to the geographical coordinates.

We hope it is useful to you.

Kind wishes,
