Inversion of satellite magnetic data for flow in the Earth's core




Greater Copenhagen area

The Earth's magnetic field is generated by a self-sustaining dynamo in the Earth's core, whereby flows of liquid metal induce planetary scale electrical currents.

The flow in the core can be inferred from changes in the Earth's magnetic field, but its detailed structure and time-dependence is still poorly know, limiting our ability to predict future changes of the geomagnetic field.

In this project a new method of inverting satellite magnetic data for core flows will be developed, making use of prior information on the influence of rotation on core dynamics, and utlizing L1 (sparsity) regularization.

Technical University of Denmark

For almost two centuries DTU, Technical University of Denmark, has been dedicated to fulfilling the vision of H.C. Ørsted – the father of electromagnetism – who founded the university in 1829 to develop and create value using the natural sciences and the technical sciences to benefit society.

Today, DTU is ranked as one of the foremost technical universities in Europe, continues to set new records in the number of publications, and persistently increases and develops our partnerships with industry, and assignments accomplished by DTU’s public sector consultancy.
