Each file in this dataset corresponds to one measurement point and is provided in ASCII format, containing both acquisition metadata and spectral quantities. The filename indicates the site ID (for example: HV_DMT_1.asc).nnPolarization parameters were estimated using the covariance matrix method, in two frequency bands: 0.2–1 Hz and 1–5 Hz. Each file corresponds to one measurement site and one frequency band. The filename indicates the site ID and the frequency band (for example: DMT01_pol_0.2_1Hz.dat; DMT01_pol_1_5Hz.dat).nnThe methodological details are described in:nnPetrosino, S., Madonia, P., Gucciardo, D., and Cusano, P.
