Update the ray geometry d. Repeat the exercise δt = Tobs − T3Dref so the travel time residual becomes δt ≅ ∫ ∆sdl where ∆s = s − s3Dref 3Drefpath This is normally done once or twice for global, long wavelength tomography and Earth and Planetary Sciences 166. When we consider the propagating waves are plane waves, we can find a coordinate system which has ∂ui/∂x2 = 0. (Image courtesy of USGS.). 1 Introduction.
