Summary
3DLGL-TPESv (version 2022-11) is the latest Sv wave model of the upper mantle and transition zone based on the waveform modeling of 2,008,820 Rayleigh waves recorded between 1976 and November 2022. The use of approximate forward theory and modeling allows updating the model following the publication of the monthly CMT catalog. The model contains azimuthal anisotropy and achieves a lateral resolution of ~600 km in the upper mantle.

| Short Description | 3DLGL-TPESv (version 2022-11) is the latest update of our background model (version 2018-08) up to November 2022. It is based on the waveform modeling of 2,008,820 Rayleigh waves recorded between 1976 and November 2022. The tomographic model is built using the same automated scheme as background model presented in Debayle et al., GRL 2016. |

| Data Set Description | We requested records from IRIS and RESIF data centers starting from the CMT catalog issued at the Lamont-Doherty Earth Observatory of Columbia University. We requested all Rayleigh waveforms recorded on the LHZ channel by the virtual networks GSN_broadband, FDSN_all, and US_backbone between January 1976 and November 2022. We also used data from Program for Array Seismic Studies of the Continental Lithosphere (PASSCAL) experiments in Africa, Tibet, and New Zealand, from the SKIPPY temporary deployment in Australia and from French temporary experiments in the Horn of Africa, French Polynesia, and in the Aegean-Anatolia region. |
