Summary
LSP_Eucrust1.0 is a new high-resolution model for the European crust and uppermost mantle. It contains an isotropic shear-wave velocity model and a probabilistic model (the probability of having an interface at certain depth).

| Short Description | LSP_Eucrust1.0 is a new high-resolution model for the European crust and uppermost mantle. It contains an isotropic shear-wave velocity model and a probabilistic model (the probability of having an interface at certain depth). The model is derived by ambient noise tomography using a new collection of large dataset across Europe (4 years continuous seismic recordings from 1293 stations). The Rayleigh wave group velocity dispersions in the period range 5-150 are inverted to obtain Vs and interface probability for the crust and uppermost mantle. The model is validated by comparison with previous geophysical studies, e.g. controlled source seismology and receiver function analysis. |

| Depth Coverage | 0.5 to 79.5 km (below earth surface) | ||
| Area | Europe (latitude 34.125°N/65.925°N, longitude: 9.975°W/29.925°E) | ||
| Data Set Description | The raw data contains up to 4 yr (July 2012–June 2016) of continuous seismic noise recorded by 1293 broad-band stations across Europe (10°W–35°E, 30°N–70°N; see Section 7 of Lu et al. 2018 for more details). The data were obtained through the EIDA (European Integrated Data Archive) data query interface. | ||
