Description
This is the tomography dataset from "Plate-scale imaging of eastern US reveals ancient and ongoing continental deformation", submitted to Geophysical Research Letters in 2024-02. A Matlab file is included, which can also be opened using Python with Scipy loadmat function. The file contains a structure with the following fields:
lon, lat, z, vs: Velocity and positions, each with shape nlon x nlat x nz.
z_moho, z_sediment, z_lab_1150: depths to each of these layers. The LAB is to the 1150 C isotherm. Shapes are nlon x nlat.
We also include surface wave datasets produced from ambient noise tomography (Lynner and Porrit, 2019), and earthquake Helmholtz tomography (Lynner et al., 2019). See files ENAM_RAYLEIGH_ANT_LYN2017.zip and ENAM_RAYLEIGH_LYNNER_EQ_HELM.zip.
