US-SL-2014 model, Schmandt & Lin (2014), is a P and S teleseismic body-wave tomography of the mantle beneath the United States.
|Title||P and S teleseismic body-wave tomography of the mantle beneath the United States|
|Type||3-D Tomography Earth Model|
|Sub Type||P and S velocity perturbations(%)|
|Teleseismic travel-time residuals from the EarthScope Transportable Array and more than 1900 additional stations are inverted for 3-D velocity perturbations. The inversion uses frequency-dependent 3-D sensitivity kernels to map travel-time residuals, measured in multiple frequency bands, into velocity structure. A surface-wave tomography starting model was used to mitigate the potential for crustal structure to create artifacts at mantle depths.|
