Abstract We present the first 3‐D images of P‐wave radial anisotropy (RAN) and azimuthal anisotropy (AAN) down to 750‐km depth beneath Greenland and surrounding regions. Three P‐wave velocity models (isotropic, RAN, and AAN) are determined by applying a regional tomographic method to simultaneously...
