Download SeisTomoPy or use it online

We provide SeisTomoPy, a Python class and a GUI interface, in order to facilitate the visualization and comparison of tomographic models. It can be downloaded here: github.com/stephaniedurand/SeisTomoPy_V3 or used online here: fascil.univ-lyon1.fr

If used in a scientific work, please refer to:

S. Durand, R. Abreu, C. Thomas (2018) SeisTomoPy: Fast Visualization, Comparison, and Calculations in Global Tomographic Models, Seis. Res. Lett. 89 (2A), 658-667

Download our tomographic model SEISGLOB2

We provide a package (SEISGLOB2_plot_package.zip) to make maps and cross-sections in SEISGLOB2 and three other tomographic models (see examples of plots below). Let me know if there is any bug.

If used in a scientific work, please refer to:

Download our tomographic model SEISGLOB1

We provide a package (SEISGLOB1_plot_package.zip) to make maps and cross-sections in SEISGLOB1 (see examples of plots below). Let me know if there is any bug.

Download our Rayleigh phase velocity and error maps

You can download .zip files below:

-raw_data.zip: It contains *.png files that contains figures of the kernels, phase velocity maps, error maps and ray density maps at each period. The names are of this form drray.yxxx-YXXX where again (Y,y) refer to the mode and (XXX,xxx) to the period. It also contains a directory phase_velocity_maps with the *.xyz files used to make the maps (vs.YXXX.xyz ) and error_maps with the *.xyz files used to make the error maps (dvs.YXXX.xyz )

-crust_corrected_data.zip: Idem as before but containing the crust corrected data files.

Download our Rayleigh surface wave dataset

You can download .zip files below:

-without_crust_corrections.zip which contains the best raw phase velocity measurements,

-with_crust_corrections.zip which contains the best phase velocity measurements that have been corrected from the crust using the crustal model 3SMAC (Nataf & Ricard, 1996)

In both cases, we measured 60 modes and for each mode there is a intomodeT.gem.YXXX (Y indicates the mode and XXX the period) file that contains the phase velocity measurements.

Each intomodeT.gem.YXXX file is built as follows:

z01 3.920000 1996.252.11.07.18.0000.GG.SCZZ....LHZ

51.6300 -176.5600 36.5980 -121.4030
