SEITCOM-1D: An Interactive 1D Code for temperature and composition modelling of the crust and mantle from seismological data
Abstract. We present SEITCOM-1D, a software to model the Earth’s thermochemical and geophysical structure from the surface down to the core-mantle boundary (CMB). The code is designed to estimate geophysical parameters of the Earth’s crust and mantle from petrological and thermal information within a thermodynamically consistent framework and to perform forward 1D coupled geophysical-petrological modelling of the structure of the Earth. Developed in Julia Language, the open-source code is intended to be an easy-to-use, flexible, and fast. SEITCOM-1D includes tools to exploit the large repertoire of 1D seismological data available, namely: surface wave dispersion curves (of fundamental and higher modes of Rayleigh and Love waves) and receiver functions (of P, S, and SKS waves). Surface heat flow and isostatic topography can also be modelled. Four simple examples that illustrate the capabilities of the code are presented to show the sensitivity of Rayleigh wave phase velocity curves and P-to-S receiver functions to compositional and temperature variations.
The Authors provided an excellent manuscript in terms of clarity, organization and quality of the content. I admit I've enjoyed the reading and have been impressed by the work done to assembly the SEITCOM-1D code. It is exactly the type of comprehensive, flexible, fast and reliable code that was missing for the forward computation of surface waves dispersion curves and RF. I'd like to congratulate the authors for this.
I have hardly any issue to mention, except for some minor suggestions:
- The name SEITCOM-1D does not seem to be an acronym, or at least this is not reported in the text. Consider to find a more appealing name, which sounds more related to "geoscience". "SEITCOM" sounds more related to the "telecomunication" field.
- L140: 1300°C --> convert to K for consistency with the rest of the text.
- L274: explain what mantle fertility means, as not all interested readers might be familiar.
- L428: I assume that dc refers to phase velocities and dU to group velocities. Please state.
- Figure 5: missing x-label for periods
- ALL FIGURES: please make all fonts/size the same across labels. Now they seem changing from one another (e.g. in Fig8-9 the "Temperature" labels are in bold...
