(a) Example of three 1‐D profiles for properties α and β: (left) fully coupled at depth, that is, the two profiles display the same number of interfaces, positioned at the same depths; (center) partially coupled at depth, that is, the two 1‐D profiles share two common interfaces at shallow depth, but the 1‐D profile for α presents three additional interfaces, at the depth level indicated by a gray‐shaded area; and (right) fully decoupled profiles, that is, the two 1‐D profiles display a different number of interfaces at not‐coincident depth positions. (b) A structure decoupling model for properties α and β. The model is composed of seven interfaces: k 1=3, k 2=2, and k 3=2. In these examples, we are using “Depth” along one axis (here y axis), illustrating spatial variation. The same examples can be done using “Time” along x axis, to present temporal variations.
