Sensitivity kernels<br />
Sensitivity kernels show the relationship between dispersion velocities and<br />
earth structure.<br />
They are calculated by taking the partial<br />
derivative of the dispersion velocities<br />
with respect <strong>to</strong> other parameters,<br />
such as shear-wave velocity. For<br />
instance, δU/δβ is often shown here.<br />
With increasing period, surface waves<br />
become sensitive <strong>to</strong> deeper velocity<br />
structures.<br />
They are themselves dependent on the<br />
velocity structure, so it is non-linear.<br />
We will be using them later when we<br />
invert our dispersion curves for<br />
layered velocity structure.
