Description

These data files are associated with the manuscript "Effect of spatial resolution of conductivity models for GIC estimation: case study in a geological complex region", submitted to Geophysical Journal International. The files include the final 3D resistivity model, sAR30, and the predicted magnetotelluric responses for the region in southern Portugal.  The inversion model was generated using a ~30x30 km grid based on previously collected data and was processed using ModEM, a modular system for the inversion of electromagnetic geophysical data.
