Three-dimensional inversion of static-shifted magnetotelluric data

“…Zhdanov et al (2000) develop a rapid 3-D inversion algorithm based on their quasi-linear approximation of the forward modeling. Yamane et al (2000) extend their 'generalized rapid relaxation inversion' (GRRI) scheme to the 3-D problem, which originated from the RRI of Smith and Booker (1991). All these methods share a common strategy in the sense that the calculation of the full sensitivity matrix is avoided.…”
