Description

This file contains phase velocity models introduced in the following paper:

"Structure of the crust and upper mantle in Greenland and northeastern Canada: Insights from anisotropic Rayleigh-wave tomography"

Authors: Parviz Ajourlou, Fiona Darbyshire, Pascal Audet, Glenn A. Milne

The tomographic inversion yields a set of phase velocity maps for which isotropic and anisotropic terms are defined on the model grid nodes (latitude/longitude).

The phase velocities are provided in different folders named by periods, and each period folder includes the following files with the corresponding format:

dcp: Isotropic phase velocities
format: Longitude, Latitude, Average phase velocity (m/s), Phase velocity perturbation (m/s), Phase velocity perturbation (%)

dap: 2-psi anisotropy
format: Longitude, Latitude, Azimuth, 2-psi anisotropy amplitude (%)

d4p: 4-psi anisotropy
format: Longitude, Latitude, Azimuth, 4-psi anisotropy amplitude (%)
