SUMMARY

In this work we implement an inversion algorithm for Airborne Electromagnetic data in the frequency domain by using 2.5D conductivity models. We discretize Maxwell’s equations on a staggered 2D grid and solve the inverse problem by regularized minimization approach. We test the numerical accuracy of the forward solution and solve the optimization problem with a limited memory BFGS algorithm. The results of our 2D inversion are then compared to those from a well-established 1D implementation.
