Applications of tomographic velocities to static corrections have drawn much attention recently. In Computing field statics with the help of seismic tomography (Geophysical Prospecting 1987), W.N. de Amorin et al. showed that the waves refracted at the base of a low-velocity layer can be used successfully for computing and refining field static corrections. In Tomographic inversion for velocity plus statics (SEG Expanded Abstracts 1991), Livia Squires et al. pointed out that velocity variations and static shifts caused by near-surface effects and positional uncertainties can be solved simultaneously using constraint tomography.
