molentargius_explorer:

Electromagnetic induction dataset
These EMI data were collected at the Molentargius Saline Regional Nature Park (Cagliari, Italy) along a 200m straight-line path, using a CMD-Explorer (Gf-Instruments).
The dataset is stored as Matlab .mat files, the data format is the one used by the FDEMtools package.

• raw data
• smoothed data
