Surface wave dispersion measurements for the Pacific, 2023 - 2024

Synthetic and real dispersion measurements for paths across the Pacific, consists of 2 datasets; SS3DPacific_new - This is a data set of surface-wave dispersion measurements. The dispersion is measured between a synthetic reference seismogram (computed with normal-mode summation using the MINEOS software in the radial model stw105 from Kustowski et al., 2008), and a real observed seismogram. This data set is used by Latallerie et al. (2024) to build a Vs model of the Pacific upper-mantle with full 3D resolution and uncertainty using SOLA inversion (Zaroli 2016) and finite-frequency theory (Zhou 2009). Data are for a set of source-receiver pairs for frequencies ranging from 6 to 21 mHz, every 1mHz. The measurement algorithm uses the multi-taper technique (Thompson 1982). The first 5 Slepians are used (Slepian 1978). A datum is the average of measurements over these tapers, and the uncertainty is the standard deviation. SS3DPacificSyn_new - This is a data set of surface-wave dispersion measurements. The dispersion is measured between a synthetic reference seismogram (computed with normal-mode summation using the MINEOS software in the radial model stw105 from Kustowski et al., 2008), and a synthetic seismogram computed using the spectral element method software Specfem in the 3D model S362ANI from Kustowski etl al. (2018). This data set is used by Latallerie et al. (2024) in a synthetic tomography study to retrieve the Vs structure of the input 3D model S362ANI in the Pacific upper-mantle with full 3D resolution and uncertainty using SOLA inversion (Zaroli 2016) and finite-frequency theory (Zhou 2009).

Statement

The dispersion is measured between a synthetic reference seismogram (computed with normal-mode summation using the MINEOS software in the radial model stw105 from Kustowski et al., 2008), and either a real observed seismogram or a synthetic seismogram computed using the spectral element method software Specfem in the 3D model S362ANI from Kustowski etl al. (2018). Measurements are provided for source-receiver pairs for frequencies ranging from 6 to 21 mHz, every 1mHz. The measurement algorithm uses the multi-taper technique (Thompson 1982). The first 5 Slepians (Slepian 1978) are used. A datum is the average of measurements over these tapers, and the uncertainty is the standard deviation.
