DBRD_NATURE2020 contains 3 seismic models which provide the datasets for the observation of partial melt below tectonic plates. DR2020s and QsADR17s are 3D models of S-wave velocity and attenuation, respectively. These models are obtained at the same resolution. Their joint interpretation yields DBRD_MELT2020, a 3D model of the melt content in the asthenosphere.

|Data Revision||r0.1 (revision history)|
|Short Description||This dataset contains 3 seismic models: DR2020s, QsADR17 and DBRD_MELT2020. DR2020s (Debayle et al., 2020) is a global isotropic (Voigt average) S-wave model of the upper mantle based on the waveform analysis of approximately 375,000 Rayleigh waves. QsADR17 (Adenis et al., 2017) is a global model of S-wave quality factor of the upper mantle based on the same dataset and modelling approach. DBRD_MELT2020 (Debayle et al., 2020) is a global model of melt content in the upper mantle based on the simultaneous interpretation of DR2020s and QsADR17.
