This dataset contains two NetCDF4 files and one txt file:

1. AK_tti_tensor.nc: Elastic tensor for the TTI model, with variables including C11, C22, .....

2. AK_tti_independent_vars.nc: Independent variables as the output of TTI inversion. The variables include:

L:  L=Vsv^2*rho, Love modulus

gamma: Shear wave inherent anisotropy amplitude

dip: Dip angle of anisotropy folliation plane

strike: Strike angle of anisotropy foliation plane

eta: eta=F/(A-2L)

Common variables:

Longitude: Ranges from -133° to -164° with 1° interval.

Latitude: Ranges from 58.5° to 70° with 0.5° interval.

Depth: 0 to 100 with 1 km interval

layer_type: 1: Sediement layer; 2: Crystalline crust layer; 3: Uppermost mantle layer

3. AK_model_depths.txt: Depths for the base of sediment and Moho used in the inversion at each grid point.
