The ETH Zurich stores precomputed Green’s functions databases produced for 16 Martian structural background models. In addition, we distribute 13 models from the literature both with 1 s. and 5 s minimum reliable period. These databases were computed using AxiSEM (Nissen-Meyer et al., 2014), an axi-symmetric spectral element method which runs within a 2D computational domain. The synthetic seismograms for any source/event pair can be calculated using Instaseis (van Driel et al., 2015), a python library built with a fast extraction algorithm for waveforms. Instaseis makes heavy use of Obspy Python package.
To see a list of models for computing the Green’s functions databases, click on the Green’s functions databases tab below. Instructions on extracting waveforms from any of these databases are given under the How to download waveforms tab. The databases are hosted at http://instaseis.ethz.ch/marssynthetics/, and can be accessed using a database name from the table below combined with this URL. For convenience, complete connection URLs are also provided. We also host a pre-calculated set of synthetics
