How can we simulate radial/transversal(R/T) or north/east (N/E) component ambient noise recording? #3

Hello,

I am very interested in three component ambient noise recording simluation.

How can I simulate three component ambient noise recording with your scritpts?

Thank you very much.

Best regards, Xi

Dear Xi, thanks for your interest in my ambient noise package! Unfortunately, the scripts are not really suitable to simulate full 3-component ambient noise records. In the scripts, you will only find a simple forward calculator that uses the 2D Green's function for a homogeneous, lossless medium (based on Appendix E of Boschi and Weemstra, 2015, "Stationary-phase integrals in the cross correlation of ambient noise"). If you want to simulate the 3D noise field in a layered, heterogeneous medium, you will probably have to use something like SPECFM3D, so that you can obtain synthetic Love- and Rayleigh waves.
