Are the Green functions for models with a water layer available now? #83

Hi guys, Thanks for this very useful package. I'm wondering if the Green's functions for models with a water layer are available now? If so, how to access them?

Cheers, H.

Hi

I am not aware that any such database would exist in the public domain. I am also unsure if the respective boundary condition is now implemented in AxiSEM, @sstaehler can you comment?

Hi,

the boundary condition is implemented, but since AxiSEM can only have a global ocean, we were never quite certain what the usecase would be.

What do you plan?

Hi Martin and Simon, Thanks for you response. I'm thinking of using AxiSEM to simulate waves from oceanic earthquakes, their depth phases and water reverberations, if it is possible. I could put receivers onto the ocean floor since I only care about the shapes and relative times between different phases.

Cheers, Hongjian

Dear Hongijan,

you can give it a try:

Set the source depth in inparam_source to the depth of your ocean layer (or a few meter deeper to make sure that you're not in the ocean layer) and do an AxiSEM run to create an Instaseis DB

Cheers,

S
