We are excited to announce the release of the new Synthetics Engine - Syngine, a service to provide custom tailored synthetic seismograms. The service uses Instaseis to generate 3D axisymmetric synthetic seismograms from TB scale Green’s functions databases pre-comuted with AxiSEM. Our current highest resolution models are accurate between 2-100 s periods. Syngine has built in support for using real network-station locations, GCMT moment tensors, and trimming traces around seismic phases.
Next week we will be demo'ing Sygine at the IRIS booth at AGU, scheduled demos are at 2pm on Tuesday and Thursday. If you cannot make those times please stop by the booth and talk to one of the DMC representatives. We look forward to your feedback.
Syngine currently has 5 1D reference models, we are working on adding more, including some with 1 Hz resolution as well as variations with oceanic/continental crusts.
