First: SSP profiles in DW are mostly cosmetic feature. They are idealized and I doubt they affect actual sound propagation model except for SSP type and layer depth.
As for convergence zones and my SoundPropagation simulator, these effects can be demonstrated, but they were not compared with real data, so don't take the results as something correct.
I will compare them, I have some real data from books. I'm doing some improvements of the SoundPropagation now so I include descriptions of model verifications with the next version.
