10.5. Comprehensive Workflows: MobileMT

Author: Devin C. Cowan

Published: October, 2023

Here, we present a general workflow for loading, interpreting and inverting Expert Geophysics MobileMT data. We begin with CSV formatted data and local topography. Our goal is to invert the data to recover a 3D conductivity model. You may work with the tutorial dataset provided or your own data:
