Model Download MHCB.MT.DeLuciaetal2019.resistivity.nc (see metadata ), is the re-gridded (in latitude/longitude) netCDF file for the model
and MHCB-MT.zip is the above model in its original format (the model in the original inversion coordinate system).
Model Homepage None
Depth Coverage 0 to 400 km
Areal Coverage Latitude 35.5° – 43.0°, Longitude -96.0° – -81.5°
 
Data Set Description Inversion used 160 EarthScope USArray MT stations (full impedance tensors and vertical magnetic field transfer functions, period range ~10-10000 s).
Model Value Range 1e0 – 1e5 (note: there will be some values beyond these numbers, but this is the meaningful range of model values)
