“…Previously we presented and discussed several methods for interpreting CHAMP magnetic anomalies over the Pannonian basin (e.g. [5]). The analytically determined vertical gradient and downward continuation of the magnetic anomalies were presented and may be correlated with the major tectonic shown in Figure 6, e.g., Scandinavia and major is determined by using the 12 th generation of the International Geomagnetic Reference Field (IGRF) [10].…”

“…The inversion procedures are discussed [5] and [6]. The Laplacian and Gaussian model parameter distributions and the effect of regularization are presented [5] [6] and [7] showed the calculation of horizontal gradients and their interpretation, [8] pointed out that the source of the global magnetic anomalies was in the lithosphere. They applied the CHAMP magnetic measurements for their interpretation.…”

Our paper discusses the determination of total magnetic field anomalies derived from the Swarm-A satellite data; one of two low orbiting satellites of the three Swarm formations. This procedure requires several modifications. The first step is the conversion of the measured CDF data to the ASCII format. This step is followed for the selection of the data with K p index ≤ 1 +. The anomalies are determined by the removal of the IGRF from the resulting satellite data. There are two Swarm-A data sets descending (6000) orbits and ascending (5688) orbits. For our study the descending orbits were used. The calculations next step is to difference of the two-dimensional linear field Figure 3 fitted to the Swarm-A anomalies and the anomalies given in Figure 2. These anomalies are filtered by Gaussian low-pass filter. The last step of the corrections is the remove the direct component, zero spatial frequency, from the descending orbits. The anomalies and their vertical gradients are qualitatively interpreted over Central Europe and the Pannonian Basin.

We computed magnetic field gradients at satellite altitude, over Europe with emphasis on the Kursk Magnetic Anomaly (KMA). They were calculated using the CHAMP satellite total magnetic anomalies. Our computations were done to determine how the magnetic field observations data from the new ESA/Swarm satellites could be utilized to determine the structure of the magnetization of the Earth's crust, especially in the region of the KMA. Ten years of CHAMP data were used to simulate the Swarm data. An initial east magnetic anomaly gradient map of Europe was computed and subsequently the North, East and Vertical magnetic gradients for the KMA region were calculated. The vertical gradient of the KMA was also determined using Hilbert transforms. Inversion of the total KMA was derived using Simplex and Simulated Annealing algorithms. The depths of the upper and lower boundaries are calculated downward from the 324 km elevation of the satellite. Our resulting inversion depth model is a horizontal quadrangle. The maximum errors are determined by the model parameter errors.

The interpretation of the CHAMP and Swarm-A satellites magnetic anomalies is discussed. The vertical gradient of the Swarm-A anomalies is presented. The vertical gradient shows in detail the magnetic sources. The inversion of the CHAMP magnetic anomalies is also presented. The inversion shows the parameters of the selected forward model. The inversion is solved by numerical procedures: the nonlinear Simplex and Simulated Annealing methods. Possible origin of upper crust magnetization is summarized. The calculation of the error propagation is estimated.
