Hello,
first off I do not really know the answer to your problem. It intrigued me because researchers local to me do geotechnical seismic work and your question looked like that sort of data. I think it must be your responsibility to transform the data into a spherical coordinate system because paraview (if it were possible) might only provide points equally spaced and not truly representing the spatial variation of your data. How can it know the metrics for converting from computational rectilinear to spherical coords?
I did google this for you though…
best wishes and happy new year.
